4 cards from this section. Quick, good the night before a test.
What happens during the photoelectric effect?
Think about what occurs when light interacts with metal.
Define 'photon'.
Consider what light is composed of.
What key observation about the photoelectric effect indicates that light has a particle nature?
Think about the frequency needed for emission.
True or False: The energy of a photon is influenced by the intensity of light.
Recall the photoelectric effect discussions.
A metal has a work function of 3 eV. If light with a frequency of 8 x 10^14 Hz hits its surface, calculate whether electrons will be emitted and determine their maximum kinetic energy.
Consider using Planck's constant to derive energy.
Calculate the de Broglie wavelength of a proton moving at 1 x 10^7 m/s.
Remember h = 6.63 x 10^-34 J·s is Planck's constant!
