velocity of light in air = 3*10^8m/s
velosity of light in glass= x
refractive index=1.5
refractive index=velocity of light in air/velosity of light in medium
1.5=3*10^8/x
x=3*10^8/1.5
x=2*10^8m/s
velosity of light in glass= x
refractive index=1.5
refractive index=velocity of light in air/velosity of light in medium
1.5=3*10^8/x
x=3*10^8/1.5
x=2*10^8m/s
