Dispersion of light: It is this difference in

It is this difference in n value for the varying frequencies (and wavelengths) that causes the dispersion of light by a triangular prism. Violet light , being slowed down to a greater extent by the absorption and re-emission process, refracts more than red light . Learn about the phenomenon of dispersion of light by a prism, the angle of deviation, the spectral dispersive power and the refractive index. Also, understand the scattering of light and its applications, and the Raman effect. A For small A , δ=(μ−1)A Dispersion of White Light By a Prism Refraction is the bending in the path of the light when it travels from one medium to the another. The degree at which refraction will occur depends on the wavelength of the light . Each light wave has a different wavelength and will therefore deviate differently. White light is composed of light of different wavelengths (colors) i.e. violet, indigo, blue, green, yellow and red. Red has the highest wavelength and violet the ... What is Dispersion ? Dispersion is defined as the separation of white light into different colours when the light is passed through the prism. The scattering of light depends on the wavelength of the light . Therefore, it can be said that the degrees of deviation is dependent on the wavelengths.
