Which type of Electromagnetic waves on the spectrum has the highest<br> energy? Why?
Marina CMI [18]

Explanation:

Each section of the electromagnetic (EM) spectrum has characteristic energy levels, wavelengths, and frequencies associated with its photons. Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.

How does sun provide us with the energy we need to run our bodies?
dusya [7]
Well, the high energy and heat found in the photons of sunlight allow plants to make their own food, sustaining them long enough to be eaten by us, or to be eaten by animals about to be eaten by us. Plus we get direct warmth from the sun. These things mean that the sun is what keeps all organisms alive in the first place.
