Question
Light traveling in air is incident on the surface of a block of plastic at an angle of 62.7$^\circ$ to the normal and is bent so that it makes a 48.1$^\circ$ angle with the normal in the plastic. Find the speed of light in the plastic.
Step 1
We can use Snell's law to find the refractive index of the plastic. Snell's law states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the speed of light in the first medium to the speed of light Show more…
