Question

a light ray incident on the surface of a medium from air. Refractive index of the medium is √2. If angle of refraction is 30° then find the angle of incidence in air. Also calculate the speed of light in given medium.



please do it fast very urgent​

Answer 1

Answer:

speed of the medium - 2.115 × 10^8

and angle of incidence=45°

Explanation:

since we know the snell's law which is speed of medium 1/speed of medium 2=sin i/sin r=n(refractive index)

so the things which are given from this we can find the following...
