Problem
Three independent experimental observations are listed below.
I. The maximum kinetic energy of recoil electrons equals the difference between the energies of the incident and scattered photons measured independently.
II. The wavelength shift observed for a given scattering angle is the same for targets of graphite and aluminum.
III. The angular distribution of scattered light shows an interference pattern characteristic of diffraction from a grating.
Which set of observations provides the strongest evidence that light behaves as a collection of particles carrying energy and momentum?
(a) I only
(b) I and III only
(c) I and II only
(d) II and III only
