The glass hemisphere in the figure has index of refraction ng = 1.8. A laser beam is directed radially toward the interface between the glass and a thin film of material with unknown index of refraction. The light is totally internally reflected when the angle of incidence exceeds 71°. What is the index of refraction nf of the material of the thin film? material under investigation glass

A uniform thin film of alcohol (n = 1.36) lies on a flat glass plate (n = 1.56). When monochromatic light, whose wavelength can be changed, is incident normally, the reflected light is a minimum for λ = 488nm and a maximum for λ = 610nm. What is the minimum thickness of the film?

The index of refraction for a certain type of glass is 1.635 for blue light and 1.607 for red light. When a beam of white light (one that contains all colors) enters a plate of glass from the air at an incidence angle of 36.55, what is the absolute value of 6, the angle in the glass between blue and red parts of the refracted beams?

A laser beam strikes in the center of one end of a long, thin glass plate that has an index of refraction of 1.4 as shown in the figure below. Determine the number of internal reflections the beam undergoes before it exits the plate at the other end. (Assume l = 2.3 m and h = 0.21 cm. The figure is not to scale.)

A laser beam in air is incident on a glass window at an angle of 30.0° from the normal. Some of the light is reflected at the air-glass boundary and some of it is refracted. The index of refraction of the glass is n = 1.69. At what angle from the normal does the refracted light travel through the glass? Incorrect.

A light beam in air (nair = 1) is incident on a horizontal glass plate (nglass = 1.58) and the reflected ray is completely polarized. The intensity of the polarized reflected beam is measured as lo = 30.0 W/cm2. It is incident on a stack of two polarizing filters, with the polarizing axis of the first and second filters at angles of 21°and 56°, respectively, from the vertical a) What is the angle of refraction for the beam in degree?...
