these are different zones in stars one of which is the sun.  the radiation zone and the convection zone transfer heat in two different ways.  heat passes thru the radiation zone as electromagnetic radiation.  heat passes thru the convection zone as hot matter rising, cooling, falling, heating.  the radiation zone is transparant to electromagnetic radiation.\n\nhttp://en.wikipedia.org/wiki/Sun#Structure

If the energy of the light does not correspond to the difference in two energy levels in the atoms it hits, the light will pass through. The vast majority of photons are passed through the glass this way. The rest are reflected at the surface or absorbed and dispersed.

When white light (for example sun light) strikes a black object, almost all the light (all visible wavelengths) are absorbe and not re-released.  That is why a black object heats up more under the sun than a white object that reflects all visible wavelengths.  You can still see the black object because it may not be perfectly black and not all visible wavelengths are absorbed or because some of the white light is reflected at the surface without being absorbed.  For light to be absorbed, the photons must penetrate the material and interact with the electrons of the atoms and molecules it meets which absorbs either none, some or all of the photons before reflecting the rest back to your eye as black, a specific color or white light.  Also consider clear glass where the photons interact with electrons and are almost all allowed to pass through only slowing down because of the longer path - permitting lenses and magnification.

HAHAHAH ARE YOU TRYING TO TEST US?\n\nLight is a form of electromagnetic radiation: i.e. it has oscillating electric(E) and magnetic(B) fields that travel through  space at speed c with the same frequency and wavelength.\nrotational energy of light if I am not worng...I like that sh.t!!good question\nRotational energy level gaps typically\n\n \n\nDE = 10^-23 J\n\nTherefore n = 1.5 x 10^10 s^-1

I'd say option B. Each photon contains one fragment of the image. But actually, there are no such things as photon particles. The "waves" that "photon particles" create are actually part of the photon themselves.

Light energy is a form of electromagnetic radiation and is found in a segment of the (EM) electromagnetic spectrum. \n\nThe EM spectrum encompasses the entire range of ionizing and non-ionizing radiation extending in frequency from approximately 1023 hertz to 0 hertz, or in corresponding wavelengths, from 10-13 centimeter to infinity. \n\nThis spectrum includes all forms of classical non-ionizing radiation we are familiar with including ultraviolet light, VISIBLE LIGHT, infrared (light) radiation, microwaves, and radio waves. The spectrum also includes ionizing radiation such as cosmic-ray photons, gamma rays, x-rays. \n\nAt eithe end of the visible light spectrum is infared and ultraviolet light and humans cannot perceive these spectrums of light.  Red colored light is longer wavelength of light and visible violet light is shorter wavelength.\n\nFor a cool chart and more in depth descriptin of the EM spectrum check out the Goddard Space Center's special page on this topic. \n\nhttp://imagine.gsfc.nasa.gov/docs/science/science.html   Use the link that says The Electromagetic Spectrum

Refer to an electromagnetic spectrum.\nRadiation is emission and propagation and emission of energy in the form of rays or waves (http://dictionary.reference.com/search?q...\nIn other words as long as waves travel there is radiation.\nThere are two types of radiation, the ionizing (harmful) radiation and the non-ionizing (not harmful) radiation.\nYou can see it in a magnetic spectrum. High frequency and low wavelength are those ionizing radiation. High wavelenth and low frequency are those non-ionizing radiation. Penetration of these waves are dependent on their frequencies. High frequencies are able to tranmsmit objects.\nFrom the magnetic spectrum there are different kinds of waves, (from non-ionizing to ionizing) radiowaves, microwaves, infrared, white light, UV, x-rays, gamma rays cosmic rays. These waves travel in a straight line unless scattered by hitting an object or being blocked or interrupted or you know I mean.\nThat's why astronomers detect radiowaves from the outerspace.

Nothing.  Light is a form of radiation, just as are microwaves, radio waves, ultraviolet rays, x-rays and gamma rays.  However, ultraviolet, x-rays, and gamma rays contain much more energy than do light waves, so they can be damaging to biological tissue.

It is how opaque a material is.\n\nIt is measured by how much light can be seen through the material.

The energy of a photon is given by E = h*f where h is planck's constant and f is the frequency.  Since photons travel at the speed of light, c, the wavelength is just:\nlambda = c / f.\n\nThe spectrum of light goes from red to violet, where red has the lowest frequency (longest wavelength) and violet has the highest frequency (shortest wavelength).  This means that violet light has more energy per photon than red light.\n\nIn radiation heat transfer, a black body is an object that absorbs all incoming radiation and reflects none (stars are nearly black).  Also, a black body emits a spectrum of radiation based on its temperature.  A plot of monochromatic emissive power vs. wavelength shows the relative "concentration" of different wavelengths of radiation in the total output.  This plot has a characteristic shape given by Planck's Law of blackbody radiation, and it has a maximum at:\n\nlambda_max * T = 2898 micrometers * K = constant\n\nwhere T is the temperature in Kelvin\n\nThus lambda_max is inversely proportional to Temperature.  This means, as the temperature of the emitting body increases, the wavelength at which more of the energy is radiated at decreases (the frequency increases).\n\nI wish I could show you the loglog plot of monochromatic emissive power vs wavelength in Mills page 453.  It shows how low temperature bodies emit in the infrared and negligibly in the visible range and as the temperature increases, the maximum moves toward the visible range.  The sun, at 5800 K has a nice plateau maximum in the visible range which explains why being able to see light is so useful for us.  Another cool thing to see in the plot is that the curve is steeper on the low wavelength side than it is on the high wavelength side: this means that as you increase the temperature of an object, it will glow red and then white because anything hot enough to have its maximum in the violet range also has a large emissive power for everything colder than violet, so all colors of light will be present.\n\nSince a hotter body radiates at higher frequencies, in a sense violet light is "hotter" than red light.\n\nTake a look at the book (or another heat transfer engineering text).  I can't explain very well with only text.

Gamma rays, heat and, in the case of a few highly-radioactive elements, light; they glow in the dark.  Beta particles which are high-energy electrons.   Their kinetic energy can be converted into light by a phosphor such as zinc sulphide, or if they enter a transparent medium with a high refractive index, they emit blue Cerenkov radiation.  Radioactive materials are warmer than their surroundings because alpha particles, beta rays and neutrons are all fast-moving particles and when they are absorbed their kinetic energy is converted into heat.  In a nuclear reactor the heat is used to raise steam which drives a turbine.  In the thermionic generators used on deep space probes it is converted directly into about 200 watts or so of electricity.

Radio waves, radar, lasers, visible light, infrared and ultraviolet light, microwaves, X-rays and gamma rays, all travel as mass-less tiny packets of energy (photons) at the speed of light.  They can all easily pass through a perfect vacuum (as could a bullet!).  In fact photons interact with the electrons orbiting atoms and molecules and can be absorbed kicking the electrons into higher more energetic orbits or entirely out of the atoms during ionization.  When electrons return to their normal (rest) orbits in one or more steps they give up their excess energy in the form of fresh photons.  When a substance absorbs the energy of photons it will heat up and when the photons are released again the substance will cool.  When you hold up your palm to the sun, you can feel the warmth of the billions of photons that strike your hand which will quickly cool in the shade as it gives up more (infrared) photons than it receives.\n\nThe light that reaches your eye from a distant star is merely composed of photons of different wavelengths (colors) that have traveled through the near-perfect vacuum of space perhaps for years at the speed of light without interacting with any electrons.  In fact, clouds of gas in space could prevent the light from reaching you.

Both are waves. Both have an associated frequency, amplitude, wavelength etc.\n\nSound travels in a medium (air for example) and is made up of compression and rarefaction waves.\n\nLight doesn't travel in a medium (it can travel through a vacuum) and is made up of the fundamental particles photons.

Light is the only thing we see with our eyes. Electromagnetic waves are light wave, of which we see a very small branch of frequency.

Radio waves are those radiation waves not visible using the unaided eye:they are ouside of the visual range.TV stations uses radio waves to transmit a signal,but it is the TV set reciever itself that recieves that signal and processes it so that it can be seen.\nHave you ever seen a radio wave?\nThe refracting and reflecting telescopes use visual light.\nThe spectroscope breaks up visible light into its constituant colors and you can see them.\nThe universe is full of radio noise and waves that are an echo of the beginning of the universe.\nTo help you understand:all light is radiation as are all other methods of transmitting any kind of radiant force.\nX-Rays,Gamma waves,neutrons et. al. all radiate out from a source.Sunlight is merely radiation that we can see,the sun is full of radio transmissions that are unseen.\nPS:The leaves of a Black Eyed Susan radiate out from the center.
