During an experiment 5.2x1014 Hz light shines on a metal plate and the Photoelectric Effect occurs. It is determined that the stopping potential is 2 V. Determine the momentum (in N-s) a photon has at the given frequency & determine the cutoff frequency (fa)

A metal surface has a photoelectric cutoff wavelength of 325.6 nm. It is illuminated with light of wavelength 259.8 nm. What is the stopping potential?

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. J c) What is the stopping voltage for an electron with the kinetic energy you just found? V

Calculate the de Broglie wavelength (in fm) of a 5.8 MeV a particle emitted from an atomic nucleus whose diameter is approximately 1.6 × 10¯14, fm Calculate its minimum kinetic energy (in keV) according to the uncertainty principle. keV Could this particle exist inside the nucleus? Yes No Explain. m.

s) The cutoff frequency of a specific metal is known to be 0.72x1015Hz. During a photoelectric experiment, 3.7x102º photons with a wavelength of 167nm are striking a plate every second. What is the power of the photons and what is the maximum kinetic energy of the ejected electrons?
