92 Figure 35-56a shows two light rays that are initially in phase as they travel upward through a block of plastic, with wavelength 400 nm as measured in air. Light ray r, exits directly into air. However, before light ray r, exits into air, it travels through a liquid in a hollow cylinder within the plastic. Initially the height Lúq of the liquid is 40.0 um, but then the liquid begins to evaporate. Let o be the phase difference between rays r, and r, once they both exit into the air.
