In this question we have been provided by two refractive indexes.
00:06
Number one is the surface having refractive index 1 and the second surface has refractive index of 1 .33.
00:15
We will write is as 4 divided by 3.
00:19
Angle of incidence is given as 45 degrees and angle of refraction is what we have to find out.
00:28
So for this type of question we use the help of snap.
00:32
Snell's law.
00:37
A snell's law says that when a ray passes through various medium, the product of refractive index and sine function of the angle will always be constant.
00:50
He said that refractive index n, sine, theta, will be constant.
01:04
So using that logic for the surface 1, n1, sine, angle of incidence i, is equal to n2, sine, angle of refraction...
