Nature of light waves
Huygen's principle
Young's double hole experiment
Young's double slit experiment
Alternate bright and dark rings observed.
Fringe width = w = Dλ/d
D = distance betwee slits and the screen
λ = wave length of light wave
d = distance between slits.
visit for past JEE objective questions on Young's double slit experiment.
(This is an important topic on which many questions were asked.)

Optical path
Interference
Fresnel's biprism
Coherent light source
There will be a constant phase difference between the two light waves in young's double experiment
Incoherent light source
the phase differene will be random - No interference will be there
Diffraction of light
Fraunhoffer diffraction by a single slit
Fresnel diffraction
Limit of resolution
Scattering of light
Polarization of light
