Question

Refractive index of glass is3/2 . Then the speed of light in glass is???

A.3*10power 8 m/s
B.2*10power 7 m/s
C.3*10power 6 m/s
D.2*10power 8/s​

Answer 1

⟹v=2×108m/s.

We know that μ=

v

c

⟹v=

μ

c

=

3/2

3×10

8

m/s

⟹v=2×108m/s.

Answer 2

Explanation:

D)

$d)2 \times {10}^{8}m |s$
