Light in air approaches thw boundary of oil at an angle of 36.1° with respect to the normal. The light travels at a speed of 2.27x10^8 m/s through the oil. Determine the angle of refraction?

I found: #26.5°#

Explanation:

We can use Snell's Law:

#n_isin(theta_i)=n_Rsin(theta_R)#

remembering the the index of refraction gives us a factor of reduction of the speed of light in a particular medium;
so we get:
