Q.1 In Compton scattering, light hits an electron and bounces off at an angle from the incident direction. The electron was initially at rest, but gains momentum from the scattering. The scattered light has the A. Same frequency as the incident light B. Higher frequency than the incident light C. Lower frequency than the incident light D. Half the frequency of the incident light.
Q.2 In Compton scattering, a photon has both energy and momentum. What are expressions for the phonon energy (E) and the magnitude of the photon momentum? A. E = hf, p = hl B. E = hc2, p = hl C. E = hf, p = hc D. E = hf, p =h l
Q.4 What does the Principle of Complementarity say about experimental results involving light A. We need both the wave nature and the particle nature of light simultaneously to explain one aspect of a single experiment. B. We need both wave nature and particle nature to explain all experiments but do not need both simultaneously for one aspect of a single experiment. C. The principle is false, light is a wave.
