QUESTION 8 What is the maximum kinetic energy that a 30 KeV photon ( lambda = 0.0413 nm) can impart to an electron initially at rest? A. 3.16 KeV B. 9.28 KeV C. 29.4 KeV D. 6.2 KeV E. 30.0 KeV
Homework Answers
If we consider an elastic head-on collision of photon with electron at rest, all the energy of photon will be transferred to the electron.
Thus, the maximum energy that can be imparted is 30 KeV.
