X-rays are scattered from electrons in a carbon target. The measured wavelength

Question

X-rays are scattered from electrons in a carbon target. The measured wavelength shift is 1.50 x 10-3 nm. The scattering angle is 67.5o. What can you say about the energy and frequency of the scattered photons based on the increase in their wavelength?

a Both energy and frequency decrease after scattering. b Energy decreases but frequency increases c Energy increases but frequency decreases d Both energy and frequency increase e Energy and frequency are not affected. Only the direction of velocity changes.

Explanation / Answer

Energy will decrease because some energy will lose and frequency will also decrease. So a Answer
