In relation to the electromagnetic spectrum

TV uses either VHF or UHF radio waves.   So these radio waves are in the frequency range between 30 MHz and 3000 MHz.   The difference between a TV and an audio radio signal is that a TV picture is more complex than an audio transmission (voice or music), so it takes a wider band of frequencies.   The entire short-wave frequency band would only have room for a handful of TV stations, but it can accommodate thousands of audio stations, and short wave transmissions can travel all over the world.   VHF and UHF signals can't travel round the curve of the Earth, so our TV stations in New Zealand can use the same frequencies as those in, say the US, without interference.

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.

Light spectra is essentially due to the electronic levels, not the nucleus (the nucleus emission/absorption would be at much higher frequency, in the gamma range); and there are no notable difference between the electronic energy level due to the extra neutron deuterium has in its nucleus; therefore very little difference in the visible band between protium and deuterium.

All kinds of electromagnetic radiation reflect as light.\nSo do microwaves.\n\nTh

The wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength. That number, also known as the frequency, will be larger for a short-wavelength wave than for a long-wavelength wave. \n\nThe equation that relates wavelength and frequency for electromagnetic waves is: λν=c where λ is the wavelength, ν is the frequency and c is the speed of light.

Infra red - used for heating\n\nMicrowaves and radar - used for cooking and, erm, for radar. :) 802.11b/g LANs, bluetooth, portable telephones, baby monitors, satellite TV, satellite communications, and a host of other devices also operate in these frequencies\n\nTV and FM radio\n\nShortwave radio\n\nAM radio\n\nAircraft and Shipping radio bands \n\nExtremely low frequency -- very long wavelengths can be used to punch small amounts of information through to a receiver in extreme conditions.  The navy had an ELF system for the purpose of giving orders to launch nukes to submarines.  This system has reportedly been abandoned.\n\nSee "sources".

Isolated atoms can absorb and emit packets of electromagnetic radiation having discrete energies dictated by the detailed atomic structure of the atoms. When the corresponding light is passed through a prism or spectrograph it is separated spatially according to wavelength.\n\nThe corresponding spectrum may exhibit a continuum, or may have superposed on the continuum bright lines (an emission spectrum) or dark lines (an absorption spectrum). \n\nThus, emission spectra are produced by thin gases in which the atoms do not experience many collisions (because of the low density). The emission lines correspond to photons of discrete energies that are emitted when excited atomic states in the gas make transitions back to lower-lying levels.\n\nAn absorption spectrum occurs when light passes through a cold, dilute gas and atoms in the gas absorb at characteristic frequencies; since the re-emitted light is unlikely to be emitted in the same direction as the absorbed photon, this gives rise to dark lines (absence of light) in the spectrum.

Shorter wavelength=higher frequency.  I know radio waves have  longest wavelength so must be lowest frequency.  and I know from longest to shortest wavelength it is radio...IR...ROYGBlueIV..Ultra so I would guess ultraviolet has highest frequency.\nSince all electrmagnetic radiation on the spectrum moves (through a vacuum) at the speed of light, if the wavelength is longer, fewer of those wavelengths are going to pass a certain point, thus a lower frequency (or Hertz I believe is the term).  The shorter the wavelength, the more wavelengths are going to pass a certain point in one second so their freq is higher.

the wavelength is half...\n\nvavelength and frequency are inversely proportional

Very simply: Every element when heated gives off a radiation frequency that is specific to itself. When the entire spectrum of light from a star is analyzed, those frequencies representing specific elements are absorbed and show up as dark lines in specific areas. Each star has a unique pattern. After correcting for any red or blue shift ( discuss that another time), the same elements will appear in the same spectral region.

Light has different frequencies. The higher the frequency the more particle there are in that light spectrum. Purple is the highest visible spectrum and red is the lowest. So because more light particles hit an object in the blue spectrum than the red spectrum the blue spectrum will generate more heat.
