Question

Speed of light in vacuum is 3*10^8 m/s. If
the refractive index of glass be 1•5,speed of light in glass will be

Answer 1

n =c/v

where n= refractive index

c= speed of light in air/ vacuum

v= speed of light in given medium

1.5 = 3 × 10^8/ v

v = 3×10^8/ 1.5

v =1.5×10^8

hope u got the answer

Answer 2

Explanation:

RI of glass -1.5

RI OF GLASS = SPEED OF LIGHT IN AIR

-------------------------------------

SPEED OF LIGHT IN GLASS

SPEED OF LIGHT IN GLASS = 3×10^8

------------

1.5

SPEED OF LIGHT IN GLASS =2×10^8 m/s

HOPE IT HELPS :)
