Question

The refractive index of the material of the prism and liquid are 1.56 and 1.32 respectively. What will be the value of 0 for the following refraction?

$\sin θ \geq \frac{13}{11}$

$\sin θ \geq \frac{11}{13}$

$\sin θ \geq \frac{\sqrt{3}}{2}$

$\sin θ \geq \frac{1}{\sqrt{2}}$

Solution

$\sin θ \geq \frac{11}{13}$

Using the formula

$μ_{prism} = \frac{μ_{liquid}}{μ_{prism}} = \frac{1.32}{1.56} = \frac{11}{13} Now the condition for total internal reflection, occur when \sin θ \geq μ so \sin θ \geq \frac{11}{13}$
