The sun gives off a large section of the electromagnetic spectrum, so you could say it is many waves all piled together
Classical they will emit electromagnetic waves (light and radio waves). Quantum effects might limit this since if the electrons are in the ground state (or all lower states are occupied) they can not emit any photons (quanta of electromagnetic waves).
Highly energetic compared to radio waves.
cook food
Well, yes. They couldn't work if they didn't emit electromagnetic radiation in the form of radio waves.
The moon
Indirectly, by analyzing the light given off by the Sun. Typically, a hotter object will emit electromagnetic waves of higher-energy - on average, because such an object will emit a mix of many electromagnetic waves.
Microwaves are not harmful, the only time when they are harmful is if the microwave is broken, as it can then emit harmful rays.

Light waves do not emit radiation, light waves are radiation.
the sun only emit light. not the moon. it will reflect the light of the sun.
sun releases electromagnetic waves of many frequencies. e.g., x-rays, cosmic rays, gamma rays, uv, visible region, infrared radiations, micro waves and radio waves and even more........ if you have more improve this answer !
