Light Reflection and Refraction | Light Reflection and Refraction - Exercise

Question 10

A ray of light is incident on a glass slab that makes an angle of 600 with the normal. The light gets refracted after entering the glass slab and makes an angle of 450 with the normal. What is the value of refractive index?

(Refractive index = Sin i/ Sin r)

Answer is (a)

Refractive index = 𝑠𝑖𝑛i/𝑠𝑖𝑛r

= 𝑠𝑖𝑛60/𝑠𝑖𝑛45

= ( √3 /2)

(1/ √2)

= √6/2
