Huygens Principle

ह्यूजेंस का सिद्धांत

In Class 12 Physics, this topic from Chapter 10: Wave Optics explains Huygens’ principle, which treats every point on a wavefront as a source of secondary spherical wavelets. Students learn how the common tangent, or envelope, of these wavelets forms the new wavefront and determines the direction of light propagation. The principle is then used to understand the laws of reflection and refraction, and to build a foundation for analysing wave behaviour.
