The refractive index of diamond is 2.47 ...

The refractive index of diamond is `2.47` and that of glass is `1.51`. How much faster does light travel in glass than in diamond ?

Text Solution

Verified by Experts

The correct Answer is:
1.635 time
Use `v_1 = ( c)/(mu_1) and v_2 = (c )/(mu_2)`, calculate `(v_2)/(v_1)`.
