Explanation:

Light is one of the lasting mysteries of the universe even though we have tons of it to examine. The photons of light can active like a wave or like a particle.

Anyway, electromagnetic waves are a part of the light spectrum and as such usually act like light. The earth's electromagnetism is found in the lowest portions of the spectrum at what is referred to as extra low frequencies. These frequencies are measured in full meters.
