In the figure, sound waves A and B, both of wavelength λ, are initially in phase and traveling rightward, as indicated by the two rays. Wave A is reflected from four surfaces but ends up traveling in its original direction. Wave B ends in that direction after reflecting from two surfaces. Let distance L in the figure be expressed as a multiple q of λ: L = qλ. What are the (a) smallest and (b) second smallest values of q that put A and B exactly out of phase with each other after the reflections?

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?

In the figure, a sound of wavelength 0.700 m is emitted isotropically by point source S. Sound ray 1 extends directly to detector D, at distance L = 11.9 m. Sound ray 2 extends to D via a reflection (effectively a "bouncing") of the sound at a flat surface. The reflection occurs on a perpendicular bisector to the SD line, at distance d from the line. Assume that the reflection shifts the sound wave by 0.500λ. For what least value...
