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 refractive index of medium A is 1.5, and the refractive index of medium B is 2.25. As light passes from medium A into medium B _____. a. It bends towards the normal b. nothing changes. c. It bends away from the normal d. it gets reflected at the same angle it came in at
. Light travels at different speeds through materials due the refractive index of that material. ...
. Light travels at different speeds through materials due the refractive index of that material. Given that I have a transparent polymer material, would light travel faster or slower through it if it (a) have zero stress on it or (b) have a substantial, but still elastic, stress on it (say 20 MPa for HDPE)? Explain.

1- A- The refractive index of a transparent material can be determined by measuring the critical angle when the solid is in air. If θc= 41.6° what is the index of refraction of the material? B- A light ray strikes this material (from air) at an angle of 31.8° with respect to the normal of the surface. Calculate the angle of the reflected ray (in degrees). C- Calculate the angle of the refracted ray (in degrees). D- Assume now that...
