Their are two laws of refraction of light......
1... Normal, incident and refracted ray all lie on same plane and the second one is snell's law....... Which states that the sine of angle of incidence to the sine of angle of refraction is constant......
Refractive index=speed of light in vacuum /speed of light in the medium.....
Given refractive index...... 1.5
1.5=3×10^8 ms^-1..../speed of light in the medium.
The answer will be.... 2×10^8ms^-1...
HOPE IT HELPS YOU!
