![]() Monochromaticity The diffraction can be obtained using both monochromatic and polychromatic light. There will be a change in the velocity of the incident light as the light is travelling between the two mediums of different refractive indices. ![]() The velocity of the light The velocity of the light before and after diffraction of light remains constant, i.e., diffraction does not affect the velocity. ![]() The light with a shorter wavelength disperse first, and then, in increasing order, they spread out of the medium. The spreading up of light waves depends on their wavelength. Dependency on wavelength Diffraction depends on the wavelength of the incident light, as if the light wave of longer wavelength is incident on the slit, it diffracts more. The propagation of light waves from one medium to another medium of different refractive indices splits into different wavelengths. Diffraction Dispersion Definition When the light strikes the edge of the hurdle, it bends at the corner, creating the geometrical fringes. The table given below helps you to understand the differences and also similarities between diffraction vs dispersion. In this post, we give a brief comparison of diffraction vs dispersion of light and their behavior. Both terms sound similar, but there are certain natures that differ them from one another. The light wave has the ability to bend and then spread out itself this behavior of light can be distinguished as diffraction and dispersion. In optics, the study of diffraction and dispersion helps us understand the behavior of light, such as the bending and spreading of light when it passes through a medium.
