Light travels from material #1 with refractive index n1 and incidence angle θ1 into material #2 with refractive index n2 and refraction angle θ2. Choose the correct statement below. If θ1 < θ2, then material #1 has a smaller index of refraction. If θ1 > θ2, then material #1 has a larger index of refraction. If θ1 > θ2, then material #1 has a smaller index of refraction. If θ1 < θ2, then light travels slower in material #2. If...

The rhinestones in costume jewelry are glass with index of refraction 1.50. To make them more reflective, they are often coated with a layer of silicon monoxide of index of refraction 2.00. What is the minimum coating thickness needed to ensure that light of wavelength 539 nm and of perpendicular incidence will be reflected from the two surfaces of the coating with fully constructive interference?
The refractive index of a transparent material can be determined by measuring the critical angle when the solid is in air. If θc= 40.3° what is the index of refraction of the material?

The angle of incidence at a solid/liquid boundary is 63.9°, and the index of refraction of the solid is n = 1.53. (a) What must be the index of refraction of the liquid such that the direction of the light entering the liquid is not changed? (b) What is the largest index of refraction that the liquid can have, such that none of the light is transmitted into the liquid and all of it is reflected back into the solid?
corrective Lenses (@) Spectacles are often coated to reduce reflection. The plastic of the lens has a very thin coating of some other material with different refractive index (as shown in the figure). 11 T2 Air ni Coating TLV n2 Lens n3 Figure - cross section showing three parallel layers of material (air, coating and the lens), with a light ray incident on the coating. The ray is partially reflected at the air/coating interface; the reflected ray Ti is shown....
