Question

As shown in the figure, after passing through the medium 1 . The speed of light v 2 in medium 2 will be : (Given c = 3 × 10 8 m s - 1 ), 1 . 0 × 10 8 m s - 1, 0 . 5 × 10 8 m s - 1, 1 . 5 × 10 8 m s - 1, 3 . 0 × 10 8 m s - 1

MARKS App · Accepted Answer

The refractive index of a medium is given by, n = μ r ε r . For medium 2 , n 2 = 1 × 9 = 3 Now speed of light in a medium will be, c v = n ⇒ v = 3 × 10 8 3 = 1 × 10 8 m s - 1
