Answer:
2×10^8
Explanation:
refractive index(n)=1.5
speed of light in vaccum(c)=3×10^8
speed of light in glass(v)=??
to find it we have a formula
n=c/v
1.5=3×10^8/v
1.5v=3×10^8
v=2×10^8

Answer:
Refractive index of a medium (nm) = Speed of light in vacuum/Speed of light in the medium
Speed of light in vacuum (c) = 3 × 108 m/s
Refractive index of glass (ng) = 1.50
Speed of light in the glass (v) = Speed of light in vacuum/ Refractive index of glass
= c/ng
=3 × 108/1.50 = 2x 108 ms-1.
