What can we say about energy on the low end of the
electromagnetic spectrum?

A. They have longer wavelengths and less dangers.

B. They have lower frequencies and more energy.

C. They have shorter wavelengths and less dangers.

D. They have higher frequencies and more energy.

A. Longer wavelengths and less dangers

Explanation:

Radio waves are at the lowest end of the EM spectrum, they have the longest wavelength of any other EM waves, the lowest energy and, accordingly, the lowest frequency;

Their low energy and frequency means they pose little risk of harm or danger as they don't get absorbed by human being.

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
