Question:
A light ray travels inside a block of sodium fluoride that has index of refraction \(n=1.33\) as shown in Figure \(\mathrm{P} 18.16\). The ray strikes the vertical wall at the critical angle, totally reflects, and then emerges into the air above the block. What is the angle \(\theta_{2}\) at which the ray emerges?
