Class 12PhysicsWave Optics
Huygens' Wave Theory
Every point on a wavefront acts as a source of secondary wavelets. The new wavefront is the tangent to all secondary wavelets. Explains: reflection, refraction, interference, diffraction — things that particle theory of light CANNOT explain. Speed of light in medium = c/n where n = refractive index. λ_medium = λ_vacuum/n.
