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.
