Exam 23: Wave Properties of Light

Two polarizing films are crossed with their transmission axes making an angle of θ = 20° with each other. The vectors that represent the plane-polarized wave train passed by the second polarizing film are

The interference and diffraction envelopes of a double slit are shown separately but to the same scale in the figure. For this arrangement, the number of fringes in the second diffraction maximum is

An air prism is immersed in water. A ray of monochromatic light strikes one face as shown. The emerging ray is

In dealing with the diffraction pattern of a single slit, we are usually interested in the location of the first minimum in light intensity because

The index of refraction of a sample of glass cannot be determined by measuring the

Diffraction of sound waves is more readily observable than that of light waves because

Two side-by-side coherent light sources radiate at 480 nm. At a point in space where the path difference to these two sources is 50 nm, the phase difference could be

The wavelength of light that has a photon energy of 4.25 eV is

The energy of an electromagnetic wave that is in the red region of the visible spectrum is approximately

Laser light passes through a circular aperture. If the brightness of the light is increased, the width of the central dark fringe will

The interference pattern is from a spherical lens placed on a flat reflecting surface using a monochromatic light of wavelength λ = 550 nm. If the distance from the center to A is 0.6 mm, the radius of curvature of the lens is

Two polarizers have their transmission axes at an angle θ. Unpolarized light of intensity I is incident on the first polarizer. What is the intensity of the light transmitted by the second polarizer?

When the slits in Young's experiment are moved closer together, the fringes

A 60° prism has a refractive index of 1.52. Calculate the angle of incidence for the initial light ray that is then refracted inside the prism and just undergoes total internal reflection at the opposite face of the prism.

A ray of light is shown reflected and refracted at the surface of a liquid. From the diagram you can determine that the speed of light in this liquid is approximately

The eyes of a person with normal vision have an angular resolution of 1/60)^o. For a person who cannot resolve as many details on an eye chart as a person with normal vision, that angle will

You place a point source of light at the bottom of a pool of water 1.00 m deep. The source emits rays upward in all directions. You notice that a circle of light is formed by the rays that are refracted into the air and that the rays outside of this circle are reflected back into the water. The index of refraction of water is 1.33. The radius R of the circle at the surface of the water is approximately

The minimum angle of deviation produced by a glass prism n = 1.70 for the light used) whose apex angle is 45º is approximately

A light wave traveling in air impinges on an amber plate at an angle of incidence of 60º. If the angle of refraction is 34º, the velocity of light in amber must be approximately

A ray of light passes from air into water, striking the surface of the water with an angle of incidence of 45º. Which of the following four quantities change as the light enters the water: 1) wavelength, 2) frequency, 3) speed of propagation, and 4) direction of propagation?
