What type of radiation does the universe emit the most?
Radio waves they are low frequencey; and it is what is emitted at very low temperatures
Which type of radiation does not ionise substances?
Any wave has an associated particle, and vice versa. However, at very low energies - such as radio waves - the wave nature stands out more; the particle nature is hard to detect in such a case.
What electromagnetic radiation is the least energetic?
Perhaps you mean one of these, I can't tell:Alpha particle radiation: least penetrating ionizing radiation, 100% shielding provided by one sheet of paper.ELF radio: lowest energy radio waves (~0.01Hz), travels long distances and through water. U.S. Navy experimented with it for communicating with Submarines.Red light: Lowest frequency of visible light.Violet light: Shortest wavelength of visible light.Very High Energy Gamma radiation: Shortest wavelength of any known radiation.Anyway, least in what way?

is light the only electromagnetic wave?
No. Visible light is actually a very small part of the electromagnetic spectrum which ranges from very short wavelength high frequency electromagnetic waves such as gamma radiation up to very long wavelength, low frequency electromagnetic waves such as radio waves. For more information on the electromagnetic spectrum and the small part of it made up of visible light, see the related link.
Answer for radiation from gamma to radio waves?
Gamma rays are very high energetic rays whereas radio waves are very weak in strength. However, radio waves can travel far distances and have large wavelength. Radio waves have large application in the field of telecommunication.

Radio waves they are low frequencey; and it is what is emitted at very low temperatures
What electromagnetic waves are produced by stars and galaxies?
Since all such emissions are "black body radiation" (or pretty close), the correct answer is "light". All wavelengths... from the longest radio waves, to very energetic gamma radiation.
How do very long radio waves reach stations beyond the curvature of the Earth?
Radio waves, like all forms of electro magnetic radiation are affected by gravity, so the Earth's mass helps to bend the radio waves to an extent. Beyond that, radio waves can be reflected naturally by atmospheric conditions, but generally, when a radio signal needs to be transmitted a significant distance, it is done by a series of radio towers in relay.AnswerThe condition is called 'skip'. The waves bounce off the ionisphere and back to earth way past the curvature.
Why does gamma radiation damage body cells but radio waves do not?
The energy of a electromagnetic wave increases as the wavelength decreases. Radio waves have a very long wavelength compared to gamma rays. Since gamma rays have so much energy, they can change molecules by "kicking out" electrons with their energy. Where as radio waves don't have enough energy to effect many compounds.
How do microwave oven cook what is the nature of radiation in microwave ovens?
It is radio waves, at the frequency of 2.45 GHz, and very high power.
Which type of radiation does not ionise substances?
Any wave has an associated particle, and vice versa. However, at very low energies - such as radio waves - the wave nature stands out more; the particle nature is hard to detect in such a case.
Are radio waves healthy for humans?
not for a long time. they are not very harmful as they have a long wavelength and a low frequency.
What are electramoganentic made of?
Electromagnetic radiation is made of energy. Very small amount of energy for radio waves or large amounts of energy for gamma rays. Visible light is electromagnetic radiation.
How Do sunspote relate to the incidence of radio and tv disturebances?
The radiation emitted by sunspots ionizes the upper layers of the Earth's atmosphere. When that happens, radio waves (TV & radio) refract (bend) more in the ionization rather than shoot off into outer space as much. The radio waves by bending back to Earth travel much farther than if they just went straight. In the right conditions, these bent radio waves can bounce up off the Earth's surface and refract again in the ionized layers of the atmosphere, coming back down. In this ways, radio waves can travel long distances. The result is, that these long-distance radio waves come back to Earth where there are other radio and TV stations using the very same frequencies, and the long-distance radio waves interfere with the local programing.

How do very long radio waves reach stations beyond the curvation of the earth?
Very long radio waves (extremely low frequency) follow the curvature of the earth in a ground wave.Short wave radio waves reflect off the ionosphere and "skip". This is an entirely different effect in a different frequency band. However the two effects are sometimes confused.
