## Homework Statement

After undergoing through 90° compton scattering, the fraction of energy lost by photon is

a) 10%

b) 20%

c) 50%

d) zero

e) none of these

## Homework Equations

∆λ= h/m

_{o}c (1-cosΦ)

## The Attempt at a Solution

What i m doing is that, i get scattered photon energy and subtracting it from the total and dividing by the total. But it seems unsolvable as wave length of the photon before scattering not given
