The speed of light in a certain piece of clear plastic is?

The speed of light in a certain piece of clear plastic is 1.85 10^8 m/s. A ray of light strikes the plastic at an angle of 27掳. At what angle is the ray refracted?The speed of light in a certain piece of clear plastic is?
You need to find the index of refraction in this question - once you know it, you can use n(air)*sin(27) = n*sin(theta).





n = c/v speed of light in vacuum(or air)/speed of light in object
