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 โ things that particle theory of light CANNOT explain. Speed of light in medium = c/n where n = refractive index. ฮป_medium = ฮป_vacuum/n.
