Light is reflected from a transparent coffee table. When the angle of incidence is 53.6°, the reflected light is completely polarized parallel to the surface of the table top. What is the index of refraction of the material of the table? Number i Units

In the figure, initially unpolarized light is sent into a system of three polarizing sheets whose polarizing directions make angles of 0 = 35°, 02 = 25°, and 03 = 34° with the direction of the y axis. What percentage of the light's initial intensity is transmitted by the system? Number i Units

Components of some computers communicate with each other through optical fibers having an index of refraction n = 1.65. What time in nanoseconds is required for a signal to travel 0.17 m through such a fiber?  ns

A beam of initially unpolarized light passes through a sequence of three ideal polarizers. The angle p12 between the axes of the first and second polarizers is 23.9°, and the angle p23 between the axes of the second and third polarizers is 58.7°. P12 P23 What is the ratio of the intensity I3 of light emerging from the third polarizer to the intensity Io of light incident on the first polarizer? I3 0.2256 Io Incorrect

Polarized light passes through two rotated filters from left to right, as shown. At the point A, its intensity is Io. The polarization axis of the first polarizer makes an angle 01= 52.6° with the direction of polarization the incoming light. The polarization axis of the second polarizer makes an angle 02= 59.6° degrees with the polarization axis of the first polarizer. E Polarized В light The intensity of light at the point C is:

A.) Polarized light is incident on 5 polarizing sheets. The axis of the first polarized sheet makes an angle with the plane of polarization. Each subsequent sheet has an axis that is rotated by an angle from that of adjacent sheets. Find if 40% of the incident intensity is transmitted by the sheets. B.) Suppose you want to rotate the plane of polarization of a beam of polarized light by 82°, but you do not want the final intensity to be less than 57% of the initial intensity. What is the minimum number of polarizing sheets you must use? Assume that each sheet is rotated the same angle relative to the adjacent sheets. sheets

A.) Polarized light is incident on 6 polarizing sheets. The axis of the first polarized sheet makes an angle 0 with the plane of polarization. Each subsequent sheet has an axis that is rotated by an angle e from that of adjacent sheets. Find e if 34% of the incident intensity is transmitted by the sheets. B.) Suppose you want to rotate the plane of polarization of a beam of polarized light by 78°, but you do not want the final intensity to be less than 53% of the initial intensity. What is the minimum number of polarizing sheets you must use? Assume that each sheet is rotated the same angle relative to the adjacent sheets. sheets
