Question

Refractive index of a medium is root of 3 At what angle of incidence the angle between reflected and refracted ray will be perpendicular to each other ? ​

Answer 1

given μ=3–√μ=3

tanip=3–√tan⁡ip=3

ip=tan−1(3–√)=60∘ip=tan−1⁡(3)=60∘

r=90−ip=90−60r=90−ip=90−60

=30∘
I hope it helps u plzz mark me as brain list.
