Question

A beam of photons of wavelength 0.650 nm undergoes Compton scattering from free electrons.

What is the momentum of the photons that emerge at a 55.0° angle with respect to the incident beam?

1.02E–33 kg·m/s

4.32E–34 kg·m/s

1.02E–24 kg·m/s

9.82E+23 kg·m/s

Answer 1

Ans: 1.02 x 10^-24 kg-m/s

explanation:

We know that

P = h/lambda

P = 6.626 x 10^-34/0.65 x 10^-9 = 1.02 x 10^-24 kg-m/s

Hence, P = 1.02 x 10^-24 kg-m/s
