A light ray travels through three parallel slabs having different indices of refraction as in the following figure. The rays shown are only the refracted rays. Rank the materials according to the size of their indices of refraction, from largest to smallest. na > nb > nc nb > nc > na nc > na > nb na > nc > nb

A light ray is incident at 45° on a glass block immersed inside a liquid of refractive index nL = 1.33 as shown in the figure below. In this configuration, the refractive ray skims the bottom surface. Determine the refractive index of the glass, ng. ng 45° ng = 1.63 ng = 1.7 ng = 1.48 ng = 1.51 O ng = 1.57

A ray of light is incident at angle ?θ = 59° on the side of two stacked transparent blocks. The bottom block has index of refraction ?1n1 = 1.41. The ray enters the top block at angle ?ϕ = 40.6°. What is the index of refraction ?2n2 of the top block? Note: Angles may not be drawn to scale.

A thin beam of light makes an angle of 60° with the surface (not the normal) of a body of water (n = 1.33). Once the light beam refracts into the water what angle does the beam make with the surface of water?     30°     68°     22°     60°

The figure below shows the path of a light beam through several slabs with different indices of refraction. (n4 = 1.01) 10% = n = 1.60 n = 1.40 n = 1.20 14 (a) If 01 35.0°, what is the angle 02 of the emerging beam? 63.12 X Your response is within 10% of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy to minimize roundoff error.º

A light ray strikes a 10-cm-thick glass pane, making a 30° angle to the perpendicular to the glass as it enters.  When the ray reemerges into air on the other side of the pane, how much has it been displaced from where it would have been if the glass weren't there (this is the distance d indicated in the figure below)? A 1.25 cm B 2.23 cm C 1.94 cm D 2.46 cm

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 #2 has a larger index of refraction. If θ1 < θ2, then light travels faster in material #1. If θ1 < θ2, then material #2 has a smaller index of refraction. If θ1 < θ2, then material #1 has a smaller index of refraction. If θ1 > θ2, then light travels faster in material #2.
