Refractive Index (n) is a ratio of the speed of light in a vacuum to the speed of light in materials
such as glass, water, plastic, etc. Using Snell's Law, and given an air to glass interface with and
angle of incidence of 15 degrees, what will be the angle of refractance R if the refractive index of
the glass is 1.5 ?
Snell's Law: n; (sin I) = n, (sin R)
So, Sin R = n; (sin I) / n
And, R = arcsin (n; (sin I) / n,)
For each angle I, find angle R:
5. I=0, R =
6. I=45, R =
7. I= 60, R =
8. I = 75, R =

arcsin (1(.259)/1.5) = arcsin (.172) = 9.9 degrees
