Explanation Given data: The thickness of glass is 3.0 mm . Formula used: Write the expression for index of refraction. n = c v (1) Here, c is the speed of light in a vacuum and has the value of 3 × 10 8 m s , and v is the speed of light in the material. Write the expression for velocity. velocity = displacement time interval (2) Explanation: Refer to TABLE 17.1 in the textbook for typical indices of refraction. The value of index of refraction of glass is 1.50 . Re-arrange equation (1) as follows. v = c n Substitute 1.50 for n and 3 × 10 8 m s for c , v = 3 × 10 8 m s 1.50 = 2 × 10 8 m s Since, the displacement of light through glass material is same as the thickness of the material. displacement = thickness Modify equation (2) as follows. v = thickness time time = thickness v Substitute 3
