Question

Explain the phenomenon of dispersion.​

Answer 1

Answer:

hey mate

Explanation:

here is your answer

light of all colours travel with the same speed on free space. but when light enter a denser medium each different frequency or colour has a different speed. the red light travel the fastest and the violet light the slowest. thus the refractive index of a medium depends upon frequency and increase in frequency .

thus when white or polychromatic light in free space passes obliquely into medium different colours are refracted with different decorations.

the red light deviate the least while voilet the most. other colours have intermediate deviations.the phenemenon of separation of light into its constituent colour is called dispersion.
