In compton scattering process, the incident X -radiation is scattered at an angle 60^ . The wavelength of the scattered radiation is 0.22 Ã… . The wavelength of the incident X -radiation in Ã… units is

Step-by-step solution

For Compton effect we have the relation ₂- ₁= h m₀ c (1- ) ₁= wavelength of incident radiation ₂= wavelength of scattered radiation aligned 0.22- ₁ & =0.024(1- 60) 0.22- ₁ & =0.024 (1- 1 2 ) 0.22- ₁ & =0.024 1 2 ₁ & =0.22-0.012=0.208 Ã… aligned
