Question
With modern technology, the index of refraction of a piece of glass can be varied linearly from the front to the back surfaces. Assume the index of refraction increases from the front to the back over the thickness, t . (a) Find an expression for the time it takes light to travel through the slab and (b) evaluate your expression for a 1.0cm thick slab for which n1 = 1.1 to n 2 = 1.44. (c) Compare your value to the time it takes light to travel through the same thickness but in vacuum.
