Define dispersion of light.

Text Solution

Verified by Experts

When a beam of white light or composite light is refracted through any transparent media such as glass or water, it is split into its component colours. This phenomenon is called as "dispersion of light".

    Describe dispersal of fruit and seeds by animals.

    The beautiful phenomenon of the rainbow is a combination of different phenomena - dispersion, internal reflection and refrection of light. The rainbow appears in the sky after a rainfall. The water droplets act as small prisms. When sunlight enters the water droplets present in teh atmosphere, they refract and disperse the incident Sunlight. Then, they reflect internally inside the droplet and finally again refract it. As a collective effect of all the phenomena, the seven coloured rainbow is observed. Q. How do refraction and dispersion take place ?

    Rainbow formation or Prove that a rainbow is the combined effect of the refraction, dispersion and total internal reflection of light.
