Given Refractive index = n = 1.65
            speed of light in vaccum = 3×108 m s-1

Using,Refractive Index= speed of light in vaccum/ speed of light in glass

1.65 = 3×108 ms-1 / speed of light in glass
speed of light in glass = 3×108 /1.65
                                         =  1.8×108 m s-1

Therefore speed of light in glass is
1.8 ×108ms-1 Ans
