Why only prism can cause the dispersion of light?
As we know, that White light is radiation of heterogeneous particles with different color and wavelength. PRISM=is a triangular-shaped transparent piece of glass that is designed for wavelengths to pass through. Furthermore, prisms is such a way designed that it do not suffer from complications arising from overlapping spectral orders, like all diffracting gratings. Light tavels in a straight line,it is refracted or bent only when it pass through any medium(air,liquid,gas).Light changes speed as it moves from one medium to another (for example, from air into the glass of the prism). This speed change causes the light to be refracted and to enter the new medium at a different angle. The degree of bending of the light’s path depends on the angle that the incident beam of light makes with the surface, and on the ratio between the refractive indices of the two media. The reflection,refraction of light depends upon the frequency of its wavelength. Hence,when the white light entering the pri
