Define dispersion of light.

In the dispersion of sunlight through glass prism the __________ light deviates the most.

V_(V),V_(R ),V_(G) are the velocities of violet, red and green lights respectively, passing through a prism after dispersion of white light. Which among the following is a correct relation ?

Say TRUE or False.Rainbow is formed by dispersion of which light by water drops.

Dispersion of light is caused due to

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.
