し2 Two light waves of wavelength 789.0 nm initially in phase when traveling in air pass...
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?
