Refraction -- A light ray is incedent on a block of glass at an angle of 30 degrees
A light ray is incedent on a block of glass at an angle of 30 degrees,what is the angle of refraction.
Given: glass: 1.47
incident angle:30°
π1 sin θ1 = π2 sin θ2
I did: (1.47) sin (30)= π2 sin θ2
But I don't think this is the answer. I'm helping a friend but the problem don't say what the other medium is...
