is solar spectrum the same with electromagnetic spectrum?

Yes. those of frequency higher than infra red are absorbed by the PV. IR travels right through the silicon in the PV

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.

Nearly all objects in the universe emit, reflect and/or transmit some light. (One hypothetical exception may be dark matter.) \n\nA rainbow shows the optical (visible) part of the electromagnetic spectrum.. Sun and stars too ..\n\nEarth emits Infrared waves .. and so our bodies ..\n\nThe Sun emits a large amount of UV radiation , infrared rdiations and others ..\n\nNeutron stars and accretion disks around black holes emit X-rays, which enable us to study them.\n\nTelevision, mobile phones, wireless networking and amateur radio all use radio waves.

sure does.  wavelength changes, therefore frequency must change since they are both proportional to c, the speed of light.

it is a series of lines, due primarily to the presence of hydrogen and helium and to lesser extent carbon, nitrogen and a few others. the most important lines show up in the visible part of the EM spectrum.

Electromagnetic waves are made out of photons.  So electromagnetic waves are all essentially a form of light.  The frequency of the electromagnetic wave is what differentiates it from others.

It depends on the wavelength of the light and its energy.

Many of them are, it depends on the wavelentgh.  Shorwave radio uses the atmosphere to bounce the waves back to earth giving it a range of over 1/2 the planet.  Other wavelenghts make it though and others are absorbed.\n\nOn another note, visible light, UV light, IR waves are all electromagnetic waves and make it through one way, it all depends on the energy of the wave (wavelength/frequency)

You are right! Atomic structure has everything to do with what wavelengths are absorbed, and which ones are reflected. I works with light, and it works with radio waves... Thats how they make stealth aircraft. Funny thing about copper... when powdered and burned, it makes a pretty green color!

I would guess the sun would be the energy in SOLAR powered anything. Solar = sun

The electromagnetic spectrum is the range of all possible electromagnetic radiation. Also, the "electromagnetic spectrum" (usually just spectrum) of an object is the range of electromagnetic radiation that it emits, reflects, or transmits.\n\nThe electromagnetic spectrum, shown in the table, extends from frequencies used in the electric power grid (at the long-wavelength end) to gamma radiation (at the short-wavelength end), covering wavelengths from thousands of kilometres down to fractions of the size of an atom. It is commonly said that EM waves beyond these limits are uncommon, although this is not actually true. The 22-year sunspot cycle, for instance, produces radiation with a period of 22 years, or a frequency of 1.4*10-9 Hz. At the other extreme, photons of arbitrarily high frequency may be produced by colliding electrons with positrons at appropriate energy. 1024 Hz photons can be produced today with man-made accelerators. In our universe the short wavelength limit is likely to be the Planck length, and the long wavelength limit the size of the universe itself (see cosmology), though in principle the spectrum is infinite.

There are two models of electromagnetic waves:  the wave model and the photon model (proposed by Einstein --> photoelectric effect... leading to quantum mechanics).  The wave model is based on a simple equation of propagation : v=f(lambda), however, there are more sophisticated equations for modelling transmition and propagation of waves based on simple harmonic motion etc... The photon model works via the principle of energy:  E(gama)= hf, where h is Planck's constant.  So, it is important to understand that radio waves and photons are 2 differnt perspectives of radiation occurring at frequencies many orders of magnitudes apart.

X-rays are just a portion of the electromagnetic radiation spectrum. Light is also part of it, as well as microwaves, radio waves, UV rays & gamma rays. Their wavelength is .1-10 nm

Yes.\nReality, as we accept, exists within a perceptible spectrum/frequency range. We can measure many other wavelengths that go unnoticed by humans. In a way, it's like insects that see in the UV or IR wavelengths. Their "reality", in this sense, is much unlike our own.\nScience has only identified X% of spectrums and, considering the numerous anomalies that occur on a regular basis, there is no telling what happens or exists in these undiscovered frequencies.\nThen again, I'm just a computer scientist, not a physicist.

you can use any part of the elecromagnetic spectrum for for solar power as long as the material can absorb it and produce electricity. \n\na crystal radio ( or even a regular radio ) uses the radio waves ( not visible ) to create a tiny current in the radio that are converted to sound waves for our pleasure.  \n\nwhat part of the spectrum used depends entirely on your choice of material.

Someone else said the colors of the visible light spectrum. This is correct. That is an acronym used to help remember the order of the light wavelengths.\n\nThe longer wavelengths on the left (Starting w/ R.)w/ red being the longest and as you move toward the right the wavelengths are shorter w/ violet being the shortest.\n\n-------Red Orange Yellow Green Blue Indigo Violet-------\nLongest<--------->Shortest\n\nThe visible light spectrum is part of the electromagnetic spectrum. It makes up a small portion of the different wavelengths.\n\nOn the shorter wavelength end you have Ultraviolet radiation, x-rays, & gamma rays. With the longer wavelengths you have infrared, microwaves, & radio waves.\n\nThe shorter wavelength, the greater amount of energy it contains & the more potentially dangerous it is.\n\nSee EM Spectrum diagram using the link below.

A radiometer does what you describe. \n\nhttp://store.sundancesolar.com/solrad.html\n\n\nDirections to build a simple radiometer:\n\nMake a radiometer to measure solar energy. Colour the paper side of a gum wrapper black and cut in four pieces. Stick the pieces to each side of a match stick with the shiny sides all facing the same way. Wrap a thread around a pencil and attach to the match stick. Suspend in the jar and place in a sunny location. The radiometer will turn as it absorbs energy.
