Problem
A medical imaging team wishes to design a scattering arrangement that will convert incident ultraviolet photons of wavelength 0.040nm into scattered photons of wavelength 0.045nm by collision with free electrons initially at rest.
(a) Determine the scattering angle θ required to obtain the desired scattered wavelength.
(b) Evaluate whether the required angle found in part (a) is physically attainable. Clearly state the range of possible angles for single-scattering events with electrons at rest and compare with your calculated value.
(c) If the angle is attainable, calculate the fractional loss in photon energy expressed as a percentage. If it is not attainable, explain quantitatively why the target scattered wavelength cannot be produced under the stated conditions.
