The velocity of light travelling in that medium = v= 107.9 m/s
What is refractive index?
It is a ratio of the velocity of light in vacuum to velocity of light in a specific medium
given
refractive index of material( u) : 2.78 * 10 ^6
c = 3* 10 ^8 m/s
velocity of light travelling in that medium(v) = ?
u = speed of light / v
v = speed of light / u
v= 3* 10 ^8 / 2.78 * 10 ^6
v= 107.9 m/s
velocity of light travelling in that medium = v= 107.9 m/s
