Question

A beam of gamma radiation having photon energy of 510 KeV is incident on a foil of Al . The wavelength of radiation at 90 degree angle is *​

Answer 1

Answer:

The wavelength of radiation at a 90° angle is 24.31nm

Explanation:

A beam of monochromatic light of wavelength \lambda (or equivalently, of frequency f) can be seen either as a classical wave or as a collection of photons that travel in a vacuum with one speed, c (the speed of light), and all carrying the same energy, {E}_{f}=hf. This idea proved useful for explaining the interactions of light with particles of matter.

Compton scattering is the main focus of this experiment, but it is necessary to understand the interactions of high energy, electromagnetic photon radiation with materials in  general. Gamma rays are high energy photons emitted from radioactive sources. When  they interact with matter, there are three primary ways their energies can be absorbed by  materials.

λ={hc}/{meC} (1-cosθ)

λ = {12400}/{510} (1-cos 90°)

λ=24.31nm
