What are different types of dispersions of light? Why do they occur? plzzzz answer me
Answers
Answer:
In an optical medium, such as fiber, there are three types of dispersion, chromatic, modal, and material. Chromatic dispersion results from the spectral width of the emitter. The spectral width determines the number of different wavelengths that are emitted from the LED or lase

The dispersion is caused due to the the difference in the angle of deviation for different colours. In the case of a glass slab, the opposite sides are parallel and therefore different colors emerge parallel to each other and are seen simultaneously.
