Mu = refractive index = sin i / sin r

Where Mu is the refractive index of medium containing r, with respect to medium containing i.

Values of i & r are between 0 and 90 deg. So Sine function is always increasing for increasing values of i or r.

If Mu is > 1 , it means i > r

If light is traveling from P to Q then

Mu = 0.95 / 0.66 = sin i / sin r i is in P and r is in Q

As Mu > 1, i is more. in Medium P, the angle is more.
