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

Re: electromagnetic radiation 2
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.

Re: electromagnetic radiation 2
Energy and wavelength are inversely proportional. Radio waves are longer, so they have less energy than UV.
Re: electromagnetic radiation 2
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.

Re: electromagnetic radiation 2
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.
