A laser beam enters a 10.0cm thick glass window at an angle of 30 degrees from the normal. The index of refraction of the glass is 1.46. At what angle from the normal does the beam travel through the glass?
sin theta 1 / sin theta 2 = n1 / n2 = v1 / v2
The Attempt at a Solution
sin (30) / sin theta 2 = 1 / 1.46
theta 2= 46.89 degrees
Not sure what I'm doing wrong here? I also tried 90 deg - 46.89 = 43.11 deg but that was also wrong.
