Question on: SS1 Physics - Wave Optics
Discuss the different types of interference patterns that can be observed in the interference of light waves.
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.
