Question

The refractive index of glass is 3by2. then find speed of light in glass? (HINT- refractive index X speed of light in medium = speed of light in vacuum. speed of light in vacuum is 3x10m/s) pls answer my question pls pls

Answer 1

Reflective index=speed of light in vacuum/speed of light in glass =3*10 to the power 8/2*10to the power 8=3/2=1.5
