Condition for Obtaining Clear and Broad Interference Bands
Condition for obtaining clear and broad interference bands (i) The screen should be as far away from the source as possible. (ii) The wavelength of…
Describe Young’s Double Slit Experiment
Young’s double slit experiment: The phenomenon of interference was first observed and demonstrated by Thomas Young in 1801. The experimental set up is shown in…
Explain on Interference of Light with Equation
Interference of light: Two slits A and B illuminated by a single monochromatic source S act as coherent sources. The waves from these two coherent…
Experiment: Total Internal Reflection by Wave Theory
Total Internal Reflection by Wave Theory: Let XY be a plane surface which separates a rarer medium (air) and a denser medium. Let the velocity…
What are the Condition for Sustained Interference?
Condition for sustained interference: The interference pattern in which the positions of maximum and minimum intensity of light remain fixed with time, is called sustained…
What are Coherent Sources?
Two sources are said to be coherent if they emit light waves of the same wavelength and start with the same phase or have a…
Define Superposition Principle
When two or more waves simultaneously pass through the same medium, each wave acts on every particle of the medium, as if the other waves…
Explain Huygen’s Principle
Huygen’s principle helps us to locate the new position and shape of the wavefront at any instant, knowing its position and shape at any previous…
Experiment: Refraction of a Plane Wavefront at a Plane Surface
Refraction of a plane wavefront at a plane surface Let XY be a plane refracting surface separating two media 1 and 2 of refractive indices…
