Question

If ratio of refractive indeces of two transparent media is 4:5.What is the ratio of speeds of light in them ?

Answer 1

Answer:

6:9

Explanation:

bcase it has a base of energy to

Answer 2

Answer:

by the formula:

( refractive of medium 1 ) ÷ (refractive index of medium 2)

= (velocity of light in medium 2 ) ÷ ( velocity of light in medium 1)

so

4 by 5 = V2 by V1

so

V1 by V2 = 5 by 4
