In a Compton scattering experiment, an x-ray photon scatters through an angle of 16.6° from a free electron that is initially at rest. The electron recoils with a speed of 2,440 km/s. (a) Calculate the wavelength of the incident photon. nm (b) Calculate the angle through which the electron scatters.

C2. A photon having energy Eo= 0.880 MeV is scattered by a free electron initially at rest such that the scattering angle of the scattered electron is equal to that of the scattered photon as shown in the figure below. (a) Determine the scattering angles (in degree) of the photon and the electron. (b) Determine the wavelength (in nm) of the scattered photon. (c) Determine the kinetic energy (in keV) of the scattered electron. Express the values to 3 significant figures, if necessary. Figure C2

A 630-nm light falls on a photoelectric surface and electrons with the maximum kinetic energy of 0.2 eV are emitted. The Plank's constant is 6.625 x 1034 J s. Then (a) Calculate the work function of the photoelectric metal surface in evV: (b) Find the cutoff frequency of the surface in Hertz: (c) When the surface of same work function as calculated above is illuminated with light of wavelength 370 nm, then find the stopping potential in Volts,
