When a light ray enters from oil to glass on oil- glass interface, then velocity of light changes by a factor of [given, _ oil =2, _ glass =3 / 2 ]

Step-by-step solution

Given, _ oil =2 and _ glass =3 / 2 velocity of light in oil is given by aligned & V _ oil = Velocity of light (c) _ oil = c _ oil Similarly, V _ glass & = c _ glass & V_ glass V _ oil = c / _ glass c / _ oil = _ oil _ glass = 2 3 / 2 = 4 3 aligned
