An artificial source of light

Natural and artificial sources of light

IF Young's experiment is performed using two separate identical sources of light instead of using two slits and one light source then the

A natural source of light

Why can’t two independent monochromatic sources of light emitting light of one and the same wavelength behave as coherent sources?

What causes a green plant exposed to the light on only one side, to bend toward the source of light as it grows

In Young's doble-slit experiment, if the monochromatic source of light is replaced by white light, then one sees

A monochromatic source of light emits light of wavelength 198 nm. Calculate : (i) energy of each photon, (ii) Momentum of the photon.
