Numerical Problems on Change in Fringe Width

Science > Physics > Interference of Light > Numerical Problems on Fringe Width In this article, we shall study numerical problems based on Young’s experiment and biprism experiment to find the fringe width of the interference pattern and to find the wavelength of light used. Example – 12: In a biprism experiment, the slit is […]

Numerical Problems on Formation of Bright and Dark Band

Science > Physics > Interference of Light > Numerical Problems on Bright and Dark Bands In this article we shall study problems, to determine the nature of interference at a point i.e. to decide whether the point is a bright point or dark point. Example – 01: The optical path difference between two identical waves […]

Interference of Light

Science > Physics > Interference of Light > Interference of Light In this article, we shall study the phenomenon of interference of light, conditions for constructive and destructive interference. Terminology: Constructive Interference of Light: When two light waves of same frequency arriving at a point, meet each other in the same phase i.e. the crest […]
