Question
An X-ray photon of wavelength l and frequency n collides with an intially stationary electron (but free to move) and bounces off. If l¢ and n¢ are respectively the wavelength and frequency of the scattered photon, then :
Options
A.λ′ = λ; ν′ = ν
B.λ′ < λ; ν′ > ν
C.λ′ > λ; ν′ > ν
D.λ′ > λ; ν′ < ν
Solution
Some of the energy of photon will be absorbed by the electron. Hence, energy of the photon will reduce correspendingly wavelength will increase and frequency decreases.
