The result of a refraction survey (Attached photo) at a site are given in the following table. Determine the thickness and P-wave velocity of the materials encountered.
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.
