Document Summary
40 kev: in a compton scattering event, the scattered photon has an energy of 120 kev and the recoiling electron has an energy of 40 kev. Find (a) the wavelength of the incident photon, (b) the angle at which the photon is scattered, and (c) the recoil angle of the electron. (a) 2 received from the sun at earth) is. 2 400km the radius of jupiter is rj and its distance from the sun is. Rj that jupiter is a perfect absorber and that it is in equilibrium with respect to energy received from the sun. 24. 3 : metal a has a work function of. , the maximum kinetic energy of electrons is. Metal b is illuminated with light of the same wavelength and the maximum kinetic energy of ejected electrons is. K b (a) what is the wavelength of the incident light? h h . 2. 3ev: in semiconductors, electrons with charge e and effective mas me can carry current.
