1 of 1

Application +4 | -1

A light ray, going through a prism with the angle of prism

60^{\circ}

, is found to deviate by

30^{\circ}

. What limit on the refractive index can be put from these data?

View answer and explanation

Correct option: B

\mu \leq \sqrt{2}

Option D (

\mu \geq \sqrt{2}

) is incorrect. The correct answer is B (

\mu \leq \sqrt{2}

) because the refractive index must be less than or equal to

\sqrt{2}

for the given deviation angle.
