Question

Refractive Index
1.33
B
1.44
С
1.52
D
1.65
In which of these four media, is the speed of light (a) minimum and (b) maximum.
Also find the refractive index of medium C with respect to medium B.​

Answer 1

Answer:

The speed of light will be minimum while passing through which of the following mediums? Notes: Light travels at approximately 300,000 kilometers per second in a vacuum, which has a refractive index of 1.0, but it slows down to 225,000 kilometers per second in water and 200,000 kilometers per second in glass.
