Discuss the different types of interference pat... - SS1 Physics Wave Optics Question

The interference of light waves can result in various types of interference patterns. Some commonly observed patterns include:

-       a) Young's Double-Slit Interference: This pattern occurs when light waves pass through two closely spaced slits. It produces a series of alternating bright and dark fringes on a screen, known as interference fringes. The pattern is characterised by equally spaced fringes, with the central fringe being the brightest.

-       b) Thin Film Interference: This pattern occurs when light waves reflect off or transmit through a thin film of material. It results in the formation of coloured fringes or bands, known as Newton's rings or thin-film interference fringes. The colours observed are due to the interference between the reflected or transmitted waves.
