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.
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 angleand report the angle as measured in degrees. If no, simply enter “-1” (exactly,without the quotes) to indicate that the critical angle does not exist.
