In comparing photons of different wavelengths, we find that the energy carried by a photon: A)increases as the wavelength increases up to a wavelength equal to λ_max, then decreases again. B)does not depend on its wavelength. C)is larger if the wavelength is shorter. D)is larger if the wavelength is longer.

Question

The energy of a photon is directly proportional to its frequency (E = hν) and inversely proportional to its wavelength (E = hc/λ). Therefore, since frequency and wavelength are inversely related, a shorter (smaller) wavelength corresponds to a higher frequency and, consequently, to a larger amount of energy carried by the photon. So the answer is choice C.
