Question 15 (1 point) Jmpton a Compton scattering experiment, an X-ray photon that has a wavelength of 0.130 nm is incident on a free, initially stationary electron. The scattered Xray photon, which has a wavelength of 0.135 nm, travels back the way the incident photon came. Before Path of incident photon Free electron * (9 li = 0.130 nm After Path of scattered photon Free electron xi: 0.135 nm What is the momentum of the free electron after the collision? '37:? 4. 91331024 kg - m/s '35:? 1. 33 so 1022 kg - m/s '37::3'5. 10 :c 1024 kg - m/s it? 1.00 cc 1023 kg - m/s Question 16 (1 point) Light with a frequency of (2.26x10A15) Hz hits a metal with a work function of (3.5000x10t0) eV.
