A certain metal has a work function of 233.0 kJ per mole of e_. What wavelength of electromagnetic radiation (in nm) must be directed at the surface in order for electrons to be ejected with a de Broglie wavelength of 14.18 angstroms (Å) 1 Å = 1×10-10 meters

How many photons with a wavelength of 450 nm is required to have a mass of 1.25 micrograms?

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?

The energy levels of an electron in an atomic-like system are given by the expression En = -C/n^p C > 0, p > 0 n = 1,2,3... If the ionization energy for the electron in its ground state is 30 eV, and a photon of wavelength 50 nm is emitted when the electron makes a transition from the third level to the ground state, find C and p.

The de Broglie wavelength of a 60 g golf ball is 4.28x10−34 m. What is its speed?

Based on your answer in Question 7, when light with a wavelength of 198 nm strikes the surface of tin metal, electrons are ejected with a maximum kinetic energy of 2.9 x 10-19  J. What is the binding energy of these electrons to the metal?
