Homework Statement
An underwater scuba diver sees the Sun at an apparent angle of 42.0° above the horizontal. What is the actual elevation angle of the Sun above the horizontal? (Use 1.333 for the index of refraction of water.)
The correct answer must be 7.86° above the horizon.
Homework Equations
Snell's law
The Attempt at a Solution
[tex]sin \theta = 1.333 \ sin (42)[/tex]
[tex]sin^{-1} (0.89) = 62.87[/tex]
Now to find the actual elevation angle [tex]90- 62.87= 27.13[/tex]
But this is wrong since the correct answer must be 7.86°. What's wrong?
