Incident X-rays have a wavelength 0.2169 nm and are scattered by the "free" electrons in graphite. The scattering angle in Figure 29.10 is theta = 132.4 degree. What is the momentum magnitude of the incident photon and the scattered photon? (For accuracy, use h = 6.626 Times 10^-34 J Times s and c = 2.998 Times 10^8 m/s.
Answers
Momentum of photon is given as
A.
There fore for incident photon
B.
Wavelength of scattered photon
Thus the momentum will be almost equal to the momentum of incident photon
= 3.05×10-24 N-s
