Consider a layer of Oil, Glass, and Air where the oil/glass boundary is parallel to the glass/air boundary. Let the index of refraction for the glass be 1.55 and the index of refraction for the oil to be 1.31.

The index of refraction. Od one medium is n(low)=1.6 & the index of refraction of an adjoining (neighbouring) medium is n(high)=2.5. Total internal reflection of light is found to occur at the boundary of these two mediums. What is the critical angle of this system at which total internal reflection occurs? Did total internal reflection go occur, should the incident angle be larger or smaller than this value? Or can it only be exactly at this angle? Within which medium must the light originate for total internal reflection to occur? AKA within which medium cab the incident light be totally internally reflected & not transmitted? -n(high) -n(low) -it doesn’t matter -not enough info
A ray of white light traveling through air enters a block of glass that has an index of refraction of 1.44 for the red end of the spectrum and 1.46 for the violet end. If the ray has an angle of incidence of 60.0 degrees with respect to the normal of the interface boundary, what's the angular separation between the red and violet ends of the spectrum within the glass?
A light ray travels inside a horizontal plate of glass, striking its upper surface at an angle of incidence of 60°. This ray is totally internally reflected at the glass-air boundary. A liquid is then poured on top of the glass. What is the largest index of refraction that the liquid could have such that the ray is stilltotally internally reflected?
A light ray in air is incident on an air-to-glass boundary with an angle of incidence of 45.0° with the normal. It is refracted in the glass with an angle of refraction of 22.0° with the normal. What is the index of refraction of the glass?
Light enters at right angle through one of the catheti of a right-angle isosceles prism which is made of glass with an index of refraction of 1.620. Because the angle of the ray with the normal when entering into the glass is zero, the ray passes straight through and strikes the interior of the hypotenuse of the prism. What is the largest value for the index of refraction of the surrounding medium which would still cause total internal reflection inside the prism?
A ray of white light traveling through air enters a triangular prism that has an index of refraction of 1.315 for the red end of the spectrum and 1.345 for the violet end and an apex angle of 72°.
