Q.1 Single Choice
The refractive index of diamond is 2.4 and refractive
index of glass is 3/2the ratio of speed of light in
diamond to the speed in glass is​

Answer 1

Explanation:

speed of light in diamond / speed of light in glass = refractive index of glass / refractive index of diamond.

1.5 / 2.4 = speed (dia) /speed( gla)

speed (dia) / speed (gla) = 15 /24 =5/8
