Question

For the same angle of incidence, the angles of refraction in media P, Q and R are 35°,

25°,15° respectively, In which medium will the velocity of light be minimum ​

Answer 1

Answer:

According to Snell's law,

Also,

<br> For given angle of incidence (i), v will be minimum, when angle of refraction r is minimum, which is for medium R.

Answer 2

Hii I will help you ✌️

=> For the same angle of incidence in media P, Q and R, the angles of refraction are 45°, 35° and 15° respectively. In which medium will the velocity of light be minimum? Give reason. For the same angle of incidence i, the refractive index will be maximum for the medium for which 'r ' is minimum i.e., for the medium R.
