Current Question (ID: 17491)

Question:
$\text{In the figure shown the angle made by the light ray with the normal in the medium of refractive index } \sqrt{2} \text{ is:}$ $n_1 = 1$ $n_2 = \sqrt{3}$ $n_3 = \sqrt{2}$ $n_4 = 2$ $n_5 = 1.6$
Options:
  • 1. $30^\circ$
  • 2. $60^\circ$
  • 3. $90^\circ$
  • 4. $\text{None of these}$
Solution:
$n_1 \sin 45^\circ = n_3 \sin \theta$ $\Rightarrow \left(1\right) \left(\frac{1}{\sqrt{2}}\right) = \sqrt{2} \sin \theta$ $\Rightarrow \sin \theta = \frac{1}{2} \Rightarrow \theta = 30^\circ$
