The refractive index of the material of the prism and liquid are 1.56 and 1.32 respectively. What will be the value of $θ$ for the following refraction?

Options:

Answer:

Solution:

Using the formula $sin (θ) = \frac{μ _{liquid}}{μ _{prism}} = \frac{1.32}{1.56} = \frac{11}{13}$ ...(1) Now the condition for total internal reflection, occur when $sin θ \geq μ$ So, $sin θ \geq \frac{11}{13}$
