How can you tell the waves from Sun are electromagnetic waves?

Below:

Explanation:

Light is a wave in the local electric and magnetic fields. Now, you can narrow that down to waves of a certain wavelength. The light we see has wavelengths of 400 to 700 nanometers, and this happens to be the types of electromagnetic waves the Sun gives off most of its energy in, and it does so pretty steadily.

Hope it helps..
