Two identical photons, each with initial wavelength

0.080\,\text{nm}

, undergo Compton scattering from free electrons. Photon A is scattered through an angle of

45^{\circ}

, and Photon B is scattered through an angle of

135^{\circ}

. Which scattered photon has the higher energy? Support your choice with a brief quantitative comparison using appropriate expressions.
