Direction of travel in glass...please please HELP!
A 0.95-cm-thick layer of water stands on a horizontal slab of glass. A light ray in the air is incident on the water 58° from the normal. What is the ray's direction of travel in the glass? (Give the answer in degrees.)
Nwater = 1.33
Nglass = 1.5
I thought this was...
sin theta 1/sin theta 2 = n2/n1
1.33/1.5 * sin 58 = 0.7519 then take the inverse of sin 0.7519 = 48.758 degrees
