In the Compton Scattering Experiment Shown in the Figure,a Monochromatic

In the Compton scattering experiment shown in the figure,a monochromatic beam of X-rays strikes a target containing free electrons.Scattered X-rays are detected with a wavelength of 2.50 × 10^-¹² m at an angle of 45° away from the original beam direction.What is the wavelength of the incident monochromatic X-rays? Note: The mass of an electron is 9.11 × 10^-³¹ kg.

A) 3.21 × 10^-¹² m
B) 2.86 × 10^-¹² m
C) 2.50 × 10^-¹² m
D) 2.03 × 10^-¹² m
E) 1.79 × 10^-¹² m
