In the figure, assume two waves
of light in air, of wavelength 556 nm, are initially in phase. One
travels through a glass layer of index of refraction
n1 = 1.57 and thickness L. The other
travels through an equally thick plastic layer of index of
refraction n2 = 1.34. What is the smallest
value L in meters should have if the waves are to end up
with a phase difference of 4.96 rad?
