According to the electromagnetic spectrum, which wavelength is associated with the lowest energy level? a.) visible b.) ultraviolet c.) gamma d.) radio

Radio waves.

Explanation:

Electromagnetic spectrum is an example of an electromagnetic waves which does not require material medium for its propagation. This electromagnetic spectrums are listed according to increase in their energy level i.e from Gamma ray to Radio waves

According to the their energy level, Gamma ray>X-ray>Ultraviolet rays>Visible light>Infrared rays>Radio waves.

This arrangement is also in terms of their increasing frequency and decreasing wavelength. This shows that radiowaves has the lowest energy level out of the electromagnetic spectrum

a) are muscles that have bands.
