Unformatted text preview: Modified from College Physics , 8 th Ed., Serway and Vuille. For the quizzes and tests, you should know all the concepts and equations in this summary. Section 24.1: Conditions for Interference Interference occurs when two or more light waves overlap at a given point. Constructive interference occurs between two waves when they are in phase (crests are on crests and troughs on troughs). Destructive interference occurs when the waves are out phase (crests are on troughs). Section 24.2: Young's Double-Slit Experiment In Young's double-slit experiment , two slits separated by distance d are illuminated by a monochromatic (one-wavelength), coherent (all the light has in the beam has the same phase) light source. An interference pattern consisting of bright and dark fringes is observed on a screen a distance L from the slits. The condition for bright (constructive interference) and dark (destructive interference) are: ( ) λ θ λ θ 2 1 sin : structive De , 2 , 1 , sin : structive Con + = ± ± = = m d...
