Okay, so we can use a derivation of snell's law to answer this question.
00:05
We're going to use the equation n1 over s plus n2 over s prime equal to n2 minus n1 over r.
00:15
So we've got the index of refraction for the diamond, in this case, the diamond, and then the air for n2.
00:29
S is going to be the position of the object, so the actual.
00:35
The actual defect, and then s prime is the image of the defect.
00:46
R refers to the radius of curvature for the boundary, and in this case, that's going to be infinity.
00:56
So we can rearrange this equation, knowing that this is infinity, we can rearrange it so that n1 over s is equal to negative n2 over s prime.
01:08
And we are trying to solve for s.
01:11
We're trying to solve for the position of the defect...
