Question

a ray of light is incident on an interface at an angle of 450 and is refracted at 300 find refractive index of rarer medium and the denser medium ​

Answer 1

Answer: refractive index of denser medium is 2

Explanation: consider the ray goes from air to some denser medium.

using sini=υsinr where i=45° and r=30°  and υ id refractive index of denser meduim with respect to air i.e is 2.

Answer 2

Answer:

Refraction identity <<<<<1 so =2

Explanation:

450-300=150/3=50°
