WebRefraction of light is the change in the direction of light as it passes from one medium to another. And when the light bounces off a medium, it is known as reflection. But, if the medium has a smooth surface, then the angle of incidence is equal to the angle of reflection. Give a daily life example of refraction of light. WebDec 15, 2024 · The dispersive medium is one in which the waves having varying frequencies travel with varying speeds. The main reason behind this condition is that due to the electromagnetic radiations, the index of refraction becomes dependent on the frequency of the waves, that is, the waves and their velocity gets heavily influenced by their …
WebPhysics; Physics questions and answers; The group speed of an electromagnetic wave packet in a particular dispersive medium is a function of angular frequency ω and is given by vgroup = c 2αω , where α is a constant and c is the speed of light in vacuum. Determine the frequency-dependent refractive index n(ω) in this medium. WebApr 19, 2024 · The group velocity is therefore u ≡ d ω / d k = ( g / k) 12 / 2 = c / 2. For the specified central wavenumber, we find that u ≈ ( 9.8 m s − 2 / 0.1 m − 1) 12 / 2 ≈ 5 m s − 1. By contrast, the phase speed of deep ocean waves with this wavelength is c ≈ 10 m s -1. Dispersive waves are waves in which the phase speed varies with ...
