The refractive index of crown glass is close to 3/2. If the speed of light in air is c, then the speed of light in the crown glass will be close to

If the speed of light in air is 3 x 10⁸ m/s, then the speed of light in a medium of refractive index 2 is

If the speed of light in air is represented by c and the speed in a medium is v, then the refractive index of the medium can be calculated using the formula

If the speed of light in carbon disulfide and vacuum is X and Y respectively, then

When a light ray enters into glass medium from water at an angle of incidence 0°, what would be the angle of refraction?

The speed of light will be minimum while passing through–
