How Does Compton Scattering Affect Photon Wavelength at 90 Degrees?

[Questions999]

Homework Statement

The length of the photon waves which are under Compton scattering ( compton scattering is applied on them) is measured in the angle =90 degree.If ΔΛ/Λ is 1.5 %,what is the length of the waves of the falling photons?

Homework Equations

The Attempt at a Solution

The only problem here is ΔΛ/Λ = 1.5 %, I don't know how to relate that to the above formula..

By definition, Δλ = (λ' - λ)/λ.

By definition, Δλ = (λ' - λ)/λ.

I think that should be Δλ = (λ' - λ) or Δλ/λ = (λ' - λ)/λ.

Right. Sorry.
