a.) A photon with kinetic energy equal to the mass energy of an electron scatters from an electron at angle ( pi/2). Find the wavelength of the scattered photon. b.) A photon with kinetic energy equal to the mass energy of an electron scatters from an electron at angle ( pi ). Find the wavelength of the scattered photon.
Radiation of a certain wavelength causes electrons with a maximum kinetic energy of 0.95 eV to be ejected from a metal whose work function is 2.55 eV. What will be the maximum kinetic energy (in eV) with which this same radiation ejects electrons from another metal whose work function is 1.81 eV? In the Compton effect, an X-ray photon of wavelength 0.16 nm is incident on a stationary electron. Upon collision with the electron, the scattered X-ray photon continues to...

5) What is the wavelength of light an electron that has an energy of 10,000 eV. What is the wavelength if it has 40,000 eV of kinetic energy. By what fraction has the wavelength changed? (me for an electron is 0.511 x10° eV] Why are electron microscopes sharper than light microscopes. Compare the wavelength of green light (520 nm) to that of the 40,000 eV electrons. How many times is the electron wavelength smaller? What would the wavelength of a...
