Question

For what value of angle of incidence a ray incident on a glass plate $(\mu =1.5)$ will the reflected ray and the refracted ray be perpendicular to each other?

• A. $\angle i={45}^{\circ }$
• B. $\angle i={30}^{\circ }$
• C. $\angle i={40}^{\circ }$
• D. $\angle i={57}^{\circ }$

Answer 1

The correct option is D $\angle i={57}^{\circ }$

$\mu =tan{i}_p,i_p={57}^{\circ }$
