Question

Assertion: Rainbow is an example of the dispersion
of sunlight by the water droplets.
Reason: Light of shorter wavelength is scattered
much more than light of larger wavelength.​

Answer 1

Answer:reason is correct bu assertion is false....

Explanation:rainbow is not only the example of dispersion but also refraction and interbal reflection along with dispersion......

Yes it is true that light of shorter wavelenght are scatered more while light of more wavelenght are scattered least......

Hope it helps u......

Answer 2

Both the assertion and the reason are true.

• The rainbow is a spectrum of light rays of seven basic colours (VIBGYOR). The white solar light ray is made out of seven basic colour rays which goes through dispersion by the water droplets of the atmosphere. And thus the rainbow is formed.
• So, the given assertion is completely true.
• Now, the light rays of seven different colours have different wavelengths, and different wavelengths causes different amounts of dispersion. Generally, the light rays which have higher wavelength goes through the minimum dispersion, and vice versa. Different amounts of dispersion causes the scattering of the light rays.
• So, the given reason is also true.
