The discussion revolves around Compton scattering and its effect on the wavelength of photons, specifically at an angle of 90 degrees. The original poster presents a problem involving the percentage change in wavelength, ΔΛ/Λ, and seeks to determine the wavelength of the photons after scattering.
Participants are exploring the definitions related to wavelength change and attempting to clarify how to use the provided percentage in the context of the problem. There is an acknowledgment of the formula for Δλ, but no consensus on its application has been reached.
There is a repeated emphasis on the percentage change in wavelength, ΔΛ/Λ = 1.5%, which appears to be a key aspect of the problem that participants are trying to interpret correctly.

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..
I think that should be Δλ = (λ' - λ) or Δλ/λ = (λ' - λ)/λ.rude man said:
