Homework Statement
A non-expanding/non-contracting laser beam having a diameter 0.132 m in air strikes a piece of glass (ng = 1.62) at an angle of 52°. What is the diameter of the beam, in m, in the glass?
Homework Equations
snell's law, n1sin(θ1)=n2sin(θ2)
The Attempt at a Solution
I get the feeling that the diameter should remain the same. I don't understand why it would be any different than that. Please let me know if I am wrong
