Chapter 24
Wave Optics
Two torches never make stripes on a wall, yet a single light and two narrow slits do. Light is a wave, and waves add up, spread round edges and can be polarised. This chapter follows Huygens' wavefronts to the laws of reflection and refraction, Young's fringes, diffraction at a slit and a grating, the limit of what a telescope can see, polarisation and thin films. It serves the Indian syllabus (NCERT, JEE Main, NEET) and the wave optics of A-Level, IB and AP Physics.
