An infrared photon has a wavelength of 900 nm. An ultraviolet photon has a wavelength of 300 nm.

The energy of the ultraviolet photon is __________the infrared photon

9 times smaller than

the same as

3 times larger than

9 times larger than

3 times smaller than

1 answer

The energy of a photon is directly proportional to its frequency, and inversely proportional to its wavelength. Since ultraviolet light has a shorter wavelength than infrared light, the ultraviolet photon will have a higher frequency and therefore higher energy.

Therefore, the energy of the ultraviolet photon is 9 times larger than the infrared photon.
