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 it.

A cathode emits electrons when it is struck by white light, which is a mixture of light of many frequencies.

A film with metallic properties becomes a better electrical conductor when light is shined upon it.

A cathode emits electrons when monochromatic light of a certain frequency strikes it.

1. The photoelectric effect experiment is often carried out by using a mercury light source to illuminate a particular surface. The emission spectrum of mercury has strong lines at wavelengths of 365.5 nm (ultraviolet), 404.7 nm (violet), 435.8 nm (blue), and 546.1 nm (green). The light can be passed through a diffraction grating to separate the light into these different wavelengths. Assume that photons of all these wavelengths have enough energy to overcome the work function of the surface. If...
