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.
