Wave optics Learning Outcomes By the end of the lesson, learners should be able: 1. To define the phenomenon of interference in wave optics. 2. To differentiate between constructive and destructive interference. 3. To explain the concepts of path difference and phase difference. 4. To identify the conditions necessary for constructive and destructive interference. 5. To apply the principles of wave interference in practical and experimental contexts. Short Note: Wave Optics Wave optics (or physical optics) deals with the wave nature of light and explains phenomena like interference, diffraction, and polarization. One of the primary phenomena in wave optics is interference, where two or more light waves superimpose to form regions of higher (constructive) or lower (destructive) intensity. Constructive Interference: Occurs when the crests or troughs of two waves coincide, resulting in increased amplitude. Destructive Interference: Happens when a crest meets a trough, canceling each ...
