75 SSM In Fig. 33-65, a light ray en- ters a glass slab at point A at incident angle e = 45.0° and then undergoes total internal reflection at point B. Air (The reflection at A is not shown.) What minimum value for the index of refraction of the glass can be in- ferred from this information? Incident ray Glass

1) Light is incident from benzene on an interface with ice. If the angle ofincidence in the benzene is 42.00°, calculate the angle of refraction in ice. 2) Is total internal reflection possible at this interface if the light is incidentthrough benzene? If the answer is yes, calculate the critical angle and report theangle as measured in degrees. If no, simply enter “-1” (exactly, without thequotes) to indicate that the critical angle does not exist. 3) Light is incident from one medium on an interface with a piece of salt (sodiumchloride). If the angle of incidence in the first medium is 69°, and the lightrefracts in the salt at an angle of 55.379°, what is the identity of the incidentmedium? A) sodium chloride B) carbon tetrachloride C) hydrogen gas D) fresh water E) zircon F) benzene G) air H) polystyrene I) ethanol J) vacuum 4) Is total internal reflection possible at this interface if the light is incident through the mystery material? If the answer is yes, calculate the critical…

(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 in air is incident at an angle of 25.0° on a glass slide with index of refraction 1.46. (a) At what angle is the ray refracted? from the normal (b) If the wavelength of the light in vacuum is 535 nm, find its wavelength in the glass. nm
