Interference in Mirrors

This lecture covers the study of interference patterns in a mirror setup, where light rays from a source are reflected and interfere with each other, forming bright and dark fringes on a screen. The instructor explains how to calculate the vertical distance between the source and the mirror, as well as the conditions for observing bright fringes. The lecture delves into the optical path length, phase differences, and the relationship between angles and fringe separation. Through trigonometry, the lecture demonstrates how to convert angular differences into spatial distances, leading to the determination of the distance between successive bright fringes on the screen.
