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...

A monochromatic, unpolarized beam of laser light is incident on a polarizer that is aligned along the vertical direction. The light has a wavelength of 355 nm. Explain in a complete sentence what fraction of the incident light passes through the polarizer? If the light coming out of this polarizer passes through a second polarizer that is rotated at an angle of 45o with respect to the first polarizer, what fraction of the original laser light will come out of...

In an experiment designed to measure the speed of light, a laser is aimed at a mirror that is 47.5 km due north. A detector is placed 116 m due east of the laser. The mirror is to be aligned so that light from the laser reflects into the detector. (a) When properly aligned, what angle should the normal to the surface of the mirror make with due south? (b) Suppose the mirror is misaligned, so that the actual angle...
