D. microwaves
E. infrared light
F. x-rays ****
looks good
To determine which type of EM radiation has the highest energy per quantum, we need to consider the electromagnetic spectrum. The electromagnetic spectrum is a range of all the possible frequencies of electromagnetic radiation.
The energy of one photon is given by the equation E = hf, where E is the energy, h is Planck's constant, and f is the frequency of the electromagnetic radiation.
Based on this equation, we can see that higher frequency radiation will have higher energy photons.
Looking at the given options:
A. FM radio and B. AM radio are both types of radio waves. Radio waves have the lowest frequencies on the electromagnetic spectrum, so they have the lowest energy per quantum.
C. Ultraviolet light has higher frequencies than radio waves, so it has higher energy per quantum than radio waves.
D. Microwaves have higher frequencies than radio waves but lower frequencies than ultraviolet light, so they have higher energy per quantum than radio waves but lower energy per quantum than ultraviolet light.
E. Infrared light has higher frequencies than microwaves, but lower frequencies than ultraviolet light, so it has higher energy per quantum than radio waves and microwaves, but lower energy per quantum than ultraviolet light.
F. X-rays have higher frequencies than all the other options listed (radio waves, microwaves, infrared light, and ultraviolet light). As a result, x-rays have the highest energy per quantum among the given options.
