Which optical effect occurs when monochromatic light bounces between the parallel glass slides of a Fabry-Pérot interferometer?

💡 Explanation

Multiple-beam interference results because wavefronts repeatedly reflect within the cavity. This constructive and destructive interference forms sharp fringes. Therefore, the effect is multiple-beam interference, rather than diffusion or polarization changes, because these involve other mechanisms.
