- A photon moving in the +x-direction, scatters off a free stationary electron. The wavelength of the incident photon is 0.0390 nm. After the collision, the electron moves at an angle a below the +x-axis, while the photon moves at an angle e = 84.3° above the +x-axis. (For the purpose of this exercise, assume that the electron is traveling slow enough that the non-relativistic relationship between momentum and velocity can be used.) (a) What is the angle a (in degrees)? |• counterclockwise from the +x-axis (b) Determine the speed of the electron (in m/s). m/sIn an x-ray tube, the maximum photon energy is given by hf = qV. Would it be technically more correct to say hf = qV + BE, where BE is the binding energy of electrons in the target anode? Why isn’t the energy stated the latter way?Please do fast ASAP fast
- An x ray of wavelength 0.050 nm scatters from a gold target. (a) Can the x ray be Compton-scattered from an electron bound by as much as 62 keV ? (b) What is the largest wavelength of scattered photon that can be observed? (c) What is the kinetic energy of the most energetic recoil electron and at what angle does it occur?When light of wavelength 240 nm falls on a tungsten surface, electrons having a maximum kinetic energy of 0.67 eV are emitted. Find values for the following. (a) the work function of tungsten ev (b) the cutoff wavelength nm (c) the frequency corresponding to the cutoff wavelength HzA photon with wavelength A 7.10 x 10 nm is incident on an electron that is initially at rest. If the photon scatters in the backward direction, what is the magnitude of the linear momentum of the electron just after the collision with the photon? (Just write the result in Sl units)
- X-rays with energy E = 340 keV are incident on a target. The x-rays undergo Compton scattering, and the scattered rays are at an angle of ? = 33.0° with respect to the incident rays. Find the Compton shift (in m) at this angle; the energy (in keV) of the scattered x-ray; and the energy (in keV) of the recoiling electron.A photon with wavelength A =7.10 x 10- nm is incident on an electron that is initially at rest. If the photon scatters in the backward direction, what is the magnitude of the linear momentum of the electron just after the collision with the photon? ( write the result in SI units)A x-ray having wavelength 0.077nm strikes a free and ‘stationary’ electron. This causes the electron to recoil and an x-ray having longer wavelength to be emitted at angle θ to the direction of the incident x-ray. If the electron recoils with kinetic energy 0.9238 eV, determine the angle at which the second x-ray emerges
