Problem 1.B.1 states:
Photons of radiofrequency radiation are higher in energy than photons of ultraviolet radiation. Why is this statement false?

Radiowaves have photons with low energy and UV light has photons with high energy. This is because radio waves have a longer wavelength and a lower frequency and UV light has a shorter wavelength and a higher frequency.

Energy and wavelength are inversely proportional. Radio waves are longer, so they have less energy than UV.

This is false since wavelength and frequency are inversely proportional. Radiowaves have a longer wavelength and lower frequency than UV light and therefore, their photons have a lower energy.

Radio waves have the lowest frequency on the EMR spectrum and therefore the lowest energy per photon. The equation E per photon = hv explains this concept.
