Question: In Figure two light pulses are sent through layers of plastic with thicknesses of either L or 2L as shown and indexes of refraction n1

In Figure two light pulses are sent through layers of plastic with thicknesses of either L or 2L as shown and indexes of refraction n1 = 1.55, n2 = 1.70, n3 = 1.60, n4 = 1.45, ns = 7.59, /t6 : I.65, and n7 = 1.50.

(a) Which pulse travels through the plastic in less time?

(b) What multiple of L/C gives the difference in the traversal times of the pulses?

-L Pulse Pulse
