A laser beam is incident on a 45°–45°–90° prism perpendicular to one of its faces, as shown in the figure below. The transmitted beam that exits the hypotenuse of the prism makes an angle of ? = 16.3° with the direction of the incident beam. Find the index of refraction of the prism.

In the figure shown, a light ray travelling through air (n=1.0) strikes the surface of an unknown material. The soeed of light in this unknown material is only 1.2E8 m)s, and the angke marked (alpha) in the figure is 30 degrees.    A) What is the index of refraction of the unknown material?   B) What is the angle marked (Beta) in the figure?       2) Draw a history graph for the position x= -2m for the same wave pulse shown in the diagram figure above. Show some mathematical proofs

A beam of light traveling through air is incident up a transparent material at an angle of ??θi=70.43 degrees as shown in the image below.  If the angle of the transmitted ray (??θt) as measured with respect to the direction normal to the surface of the material (dashed line in the image below) is 29.72 degrees, what is the index of refraction of of the material?

A ray of light enters a liquid from air. If the angle between the incident and refracted rays is 133° and the angle between the reflected and refracted rays is 76°, find the refractive index of the liquid. Assume the refractive index of air is 1.00.

A ray of light crosses the boundary between some substance with n = 1.54 and air, going from the substance into air. If the angle of incidence is 29◦ what is the angle of refraction?   Calculate to 1decimal.

A laser beam is incident on a 45°-45°-90° prism perpendicular to one of its faces, as shown in the figure below. The transmitted beam that exits the hypotenuse of the prism makes an angle of = 17.7° with the direction of the incident beam. Find the index of refraction of the prism. h Jē 45.0⁰

Light is incident from one medium with an index of refraction of 2.31 at an angle of 27.14 degrees with respect to the normal to the surface. The light then passes into another medium with a refractive index 1.35.With what angle is the light refracted with respect to the surface normal?
