Homework Statement
A green light is submerged 2.30 m beneath the surface of a liquid with an index of refraction 1.39. What is the radius of the circle from which light escapes from the liquid into the air above the surface?
Homework Equations
Critical angle: Sin(AngleCritical)=(n2/n1), n1>n2
Well I think...
The Attempt at a Solution
Is the radius a direct line of light from the light to the water's surface?
If so: sin-1(1.39/1) = 46 cos(46)*2.3=ans
