Optics Youngs Interference Experiment

Young’s Interference Experiment

Concept Explanation
Interference of light Two beams of light can interfere with each other, producing bright and dark fringes on a screen.
Two coherent sources Young’s experiment requires two coherent sources of light. These are sources that produce waves with the same wavelength and a constant phase difference.
Double slit The experiment is performed by shining a beam of light through two closely spaced slits. The slits act as two coherent sources of light.
Interference fringes The light from the two slits interferes with each other, producing bright and dark fringes on a screen placed behind the slits.
Fringe pattern The fringe pattern consists of a series of bright and dark fringes, with the central fringe being the brightest.
Path difference The path difference between the waves from the two slits determines the position of the fringes.
Fringe width The width of the fringes depends on the wavelength of light and the distance between the slits.
Double slit interference Explains wave nature of light.
