Question

5. What is the velocity of light in a medium with refractive index 1.5?
.) 2 x 10 m/s
b) 3 x 10 m/s
C) 15 x 10 m/s
d) 2.5 x 10 m/s​

Answer 1

Answer:

Explanation:

• Refractive index of a medium is its resistance to the light which results in deviation or lateral shift.

$Refractive\ index (n ) = \frac{speed of light in vaccum}{velocity of light in that medium}$

$1.5 =\frac{ 3*10^{8}m/s}{v} -- -------.[v /is /velocity/ of /light/ in /that/ medium]$

$v= 2*10^8$
