time= distance/ speed
for pulse 1,
t1=L/c( 1/n1 + 1/n2 + 1/n3 + 1/n4)
for pulse 2,
t2=L/c( 2/n5 + 1/n6 + 1/n7)
t1=L/c ( 0.621 + 0.588 + 0.606 + 0.684) =
t2=L/c (1.24 + 0.591 + 0.645)
clearly, pulse 1 takes longer time.
t1= 2.499L/c
t2=2.476L/c
They differ by a multiple of 23 (approx)

In the figure, two light pulses are sent through layers of plastic with thicknesses of either L or 2L as shown and indexes of refraction n,-1.63, n2-172, n3-1.65, n4-1.52, n5-1.68, n6-1.65, and n7-1.57. (a) which pulse travels through the plastic in greater time? (b) What multiple of L/c gives the difference in the traversal times of the pulses? Puke Puke (a) Number Units (b) Number Units

Transmission through thin layers. In the figure, light
is incident perpendicularly on a thin layer of material 2 that lies
between (thicker) materials 1 and 3. (The rays are tilted only for
clarity.) Part of the light ends up in material 3 as ray
r3 (the light does not reflect inside material
2) and r4 (the light reflects twice inside
material 2). The waves of r3 and
r4 interfere, and here we consider the type of
interference to be either...
