In a particular case of Compton scattering, a photon collides with a free electron and scatters backwards. The wavelength after the collision is exactly double the wavelength before the collision. What is the wavelength of the incident photon? (mel = 9.11 × 10-31 kg, h = 6.626 × 10-34 J ∙ s, c = 3.00 × 108 m/s) Group of answer choices 1.2 pm 4.8 pm 3.6 pm 2.4 pm

An incident X-ray photon of wavelength 0.2011 nm is scattered from an electron that is initially at rest. The photon is scattered at an angle of 0 = 180.0° in the drawing and has a wavelength of 0.2060 nm. Use the conservation of linear momentum to find the momentum gained by the electron.

Light of wavelength 340 nm, 600 nm and 680 nm is incident on a metal. Electrons are not emitted from the metal, which of the following is the most likely scenario.     The energy of the photon for 600 nm light corresponds to the work function of the material.     The energy of the photon for 680 nm light corresponds to the work function of the material.     The work function is less than any of these photon energies.     The work function is more than any of these photon energies.     The energy of the photon for 340 nm light corresponds to the work function of the material.

You set up a photoelectric experiment with an unknown metal to eject electrons. You use light of wavelength λ = 670 nm, which just BARELY ejects electrons from the metal. Planck□s constant is either h = 6.63 x 10-34 J-s or h = 4.14 x 10-15 ev.s. a) What is the binding energy of the unknown metal in eV? ev b) You change the light source to one with a wavelength of λ = 310 nm. Using the binding energy you found in the previous step, find the maximum kinetic energy of an electron that is ejected from the metal in Joules.
