The light beam shown in Figure P22.21 makes an angle of ϕ = 23.5° with the normal line NN' in the linseed oil. Determine the angles θ and θ'. (The refractive index for linseed oil is 1.48.)(adsbygoogle = window.adsbygoogle || []).push({});

The normal line makes a 90 angle with the surface of the linseed oil. The light then passes through water but I need the linseed oil angle to get the water angle.

Snell's Law

So I used 1*sin(23.5)=1.48*sin(theta) and solved for theta. I got 15.63 degrees which is incorrect
