Hello student, in this question we need to calculate the difference between the angles of refraction.
00:06
For that, using the snells law of refraction, which says that the refractive index is equal to sign of angle of incidence divided by sign of angle of refraction.
00:20
Now, using this formula, we can find the value of angle of refraction for both the cases.

Firstly, for the case of i's, let us apply the formula, we get n i equals sine theta 1 divided by sine theta 2 ice.
00:42
Now from here, the angle theta 2 is will be equal to sine inverse of sine theta 1 divided by now putting the values given in the statement, we get sine inverse of sine theta 1 is 60 degree divided by refractive index for ice is 1 .309.
01:10
Now after the calculation, we can find that the theta 2 ice, the angle of refraction, will be equal to 41 .42 degrees.

Now for the case of water, let us apply the same formula, we can find that nw equals sine of theta 1 divided by sine of theta 2 water...
