The X-rays detected at a scattering angle of theta = 163 degrees have a wavelength of 0.1867 nm . Find

a) the wavelength of an incident photon

b) the energy of an incident photon

c) the energy of a scattered photon

d) the kinetic energy of the recoil electron . (For accuracy , use h = 6.626 x 10^-24 J*s and c = 2.998 x 10^8 m/s .
