P. 4841. In case of the Compton effect ``stationary'' electrons are ``bombarded'' by photons which photons have the same energy as the rest energy of electrons. Among the above described photons there will be some whose linear momentum will be equal in magnitude to the magnitude of the linear momentum of the electrons with which the photons collided. Considering these cases determine the
\(\displaystyle a)\) angle between the scattered photons and the electrons with which the photons collided;
\(\displaystyle b)\) The speed of the electrons with which the photons collided.
