A ray of light is pointed at the surface of a block of fused quartz at an angle of 30.0° with respect to the normal (a line perpendicular to the surface at the spot where the ray hits the block). Part of the light is reflected and the rest refracted. What is the angle (in degrees) between the reflected and refracted rays?

A certain beam of light travels inside a certain type of plastic at a speed of 1.816 x 108 m/s. What is the index of refraction of the plastic?

A ray of light is incident on a flat surface of a block of cubic zirconia, with an index of refraction of 2.2, that is submerged in water. The ray is split at the surface, where the angle of refraction of the transmitted ray is 11.9°. What is the angle of reflection (in degrees) of the reflected ray?

The following figure shows a ray of light entering one end of an optical fiber at an angle of incidence θi = 49.5°. The index of refraction of the fiber is 2.04. Find the angle θ the ray makes with the normal when it reaches the curved surface of the fiber.

You send a beam of light from a material with index of refraction 1.19 into an unknown material. In order to help identify this material, you determine its index of refraction by measuring the angles of incidence and refraction for which you find the values 40.7° and 36.5°, respectively. What is the index of refraction n of the unknown material? n =

A ray of light is directed toward the surface of a block of fused quartz at an angle of 29.0° with respect to the normal (a line perpendicular to the surface at the spot where the ray hits the block). A fraction of the light is reflected and the rest refracted. What is the angle (in degrees) between the reflected and refracted rays?

The drawing illustrates the dispersion of light by a prism. The prism is made from a certain type of glass, and has a cross section shaped like an equilateral triangle. The indices of refraction for the red and violet light in this type of glass are 1.608 and 1.639, respectively. The angle of incidence for both the red and violet light is 60.0°. Find the angles of refraction at which the (a) red and (b) violet rays emerge into the air from the prism.

Physics A beam of light strikes the surface of glass (n = 1.46) at an angle of 70 degrees with respect to the normal. Find the angle of refraction inside the glass. Take the index of refraction of air n1 = 1.

A ray of light crosses the boundary between some substance with n = 1.58 and air, going from the substance into air. If the angle of incidence is 17◦ what is the angle of refraction?   Calculate to 1decimal.

The index of refraction of a plate of glass is 1.523. If the angle of incident of a light beam passing from a vacuum to the glass is 30 degrees (the angle with respect to the normal to the glass surface), what is the angle of refraction? Is the beam bent toward the normal or away from it?
