A uniaxial crystal with refractive indices no and ne is cut so that the optic axis is perpendicular to the surface as shown in the diagram. Show that for a beam incident on the interface from air at an angle of incidence, 0; that the angle of refraction of the extraordinary e - wave is sin(0;) ne tan(0.) no /n? – sin²(0;) - optic axis direction Or, Oe

A plane sound wave in air at 20°C, with wavelength 589 mm, is incident on a smooth surface of water at 25°C at an angle of incidence of 12.3°. (a) Determine the angle of refraction for the sound wave. (b). Determine, the wavelength of the sound in water. Enter a number with units. A narrow beam of sodium yellow light, with wavelength 589 nm in vacuum, is incident from air onto a smooth water surface at an angle of incidence of 12.3o. (c) Determine the angle of refraction. (d) Determine the wavelength of the light in water.

The critical angle for an air-glass interface is  29.2°. When a light ray in air is incident on the interface, the reflected ray is 100% polarized. What is the angle of refraction of that ray in degrees?  (numerical answer only with 3 sig figs please)
