Suppose light travels from water to another substance, with an angle of incidence of 10.0º and an angle of refraction of 14.9º . (a) What is the index of refraction of the other substance? (b) What is unreasonable about this result? (c) Which assumptions are unreasonable or inconsistent?

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.

(b). A ray of light passes from glass to water. The angle of incidence in the glass is 35°, take the refractive indices of glass and water to be 1.52 and1.33, respectively. (i). What is the angle of refraction in the water? (ii). At what angle will total internal reflection occur between the glass-water interface?

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 light beam containing red and violet wavelengths is incident on a slab of quartz at an angle of incidence of 56. The index of refraction of quartz is 1.455 at 660 nm (red light), and its index of refraction is 1.468 at 410 nm (violet light). Find the dispersion of the slab, which is defined as the difference in the angles of refraction for the two wavelengths.  1.31º 1.05º 0.35º 0.50º
