sin 30.4 = N sin 20.7
Solve for the index, N
It's called Snell's Law
This assumes the incident ray is in air or vacuum, where the index is 1.000
A ray of light has an angle of incidence of 30.4� degrees
on a block of quartz and an angle of refraction
of 20.7� degrees.
What is the index of refraction for this block
of quartz?
