Question

In Figure (a), a beam of light in material 1 is incident on a boundary at an angle of 28° The extent to which the light is bent due to
refraction depends, in part, on the index of refraction n2 of material 2. Figure (b) gives the angle of refraction 02 versus n2 for a range of
possible n2 values, from n, = 1.36 to n, = 1.94. What is the speed of light in material 1?
