Question
After applying sunscreen, Cherie lies in the summer sun to get a tan. The ultraviolet light responsible for tanning has a wavelength over 310. nm, while the burning rays can range down to 280. nm. Which ultraviolet photons emit more energy, those that tan or those that burn?

Answer:
The photons that burn, emit more energy.
Explanation:
The energy of the ultraviolet photons can be determined by means of the following equation:
Equation 1 can be rewritten in terms of
Since,
Where h is the planck’s constant, c is the speed of light and
is the wavelength.
Case for the photon of with
Case for the photon of with
Hence, the photons that burn, emit more energy.
