Homework Statement
A fish is 30 cm below the surface of a lake.
If he looks up he can see the entire sky compressed in a cone of angle θ, because of refraction of light at the water surface. (θ is the angle between the cone axis and the cone surface.) Determine θ.
Homework Equations
n1*sin(theta 1)=n2*sin(theta 2)
n1=1
n2=1.33
theta 1=90
theta 2=?
The Attempt at a Solution
sin(90)/1.33=sin(theta 2)
sin-1(0.672177943)=42.24 degrees
This doesn't seem to be the answer though...
Any help?
