Time taken by light to travel in two different materials A and B of refractive indices |U A and |A B of same thickness is ti and t 2 respectively. If t 2 – t 1 = 5 x 10 -10 s and the ratio of 
to 
is 1 : 2. Then the thickness of material, in meter is : (Given V A and V B are velocities of light in A and B materials respectively).
