In an experiment on the photoelectric effect, a beam of
monochromatic light is aimed at a nickel-plated cathode. A
scientist uses mathematical formulas to calculate the maximum speed
of the electrons that the cathode releases. Which constant most
limits the precision of the calculation?
the charge of one electron
the mass of an electron
the work function of nickel
Planck’s constant
Which example illustrates a behavior called
“photoconductivity”?
A metallic film conducts electricity when an electric potential
is applied across...
