Q. A photon traveling in the positive x-direction collides with a stationary free electron. The incident photon has a wavelength of 0.0310 nm. Post-collision, the electron moves at an angle ๐ผ below the positive x-axis, and the photon deflects at an angle ๐ = 66.3ยฐ above the positive x-axis. A) Calculate the angle ๐ผ (in degrees). B) Compute the velocity of the electron (in m/s). Solution:
