Compared to a radio waves, ultraviolet rays have
a.) more energy and shorter wavelengths
b.) more energy and longer wavelengths
c.) less energy and longer wavelengths
d.) less energy and shorter wavelengths

A.) more energy and shorter wavelengths.

Explanation:

Radio waves and ultraviolet rays are both part of the electromagnetic spectrum. The energy of a wave in the electromagnetic spectrum depends on the frequency of said wave, and the frequency of a wave depends on the wavelength. Shorter wavelength = higher frequency = more energy. Longer wavelength = lower frequency = less energy.

Radio waves have a longer wavelength when compared to ultraviolet rays, so therefore they have a lower frequency and less energy.

Sorry, I suck at explaining things, so I hope I made at least somewhat understandable.

the answer for apex is the lowest

the higher the current the higher the mag field around it the higher the influence on the compass
