Question

Assertion: The scattering of longer wavelengths of light increases as the size of the particles increases.

Reason :Large particles scatter lights of all wavelengths equally well.

1)Both A and R are true, and R is correct explanation of the assertion

2)Both A and R are true, but R is not the correct explanation of the assertion.

3)A is true, but R is false.

4)A is false, but R is true.​

Answer 1

Answer:

3) A is true but R is false.

Explanation:

This is because particles of smaller size scatter mostly light of smaller wavelengths (such as blue light) whereas particles of larger size scatter light of longer wavelengths (such as red).

Answer 2

Both assertion and reason are true and reason is the correct explanation of assertion.

Explanation:

• When light rays passes through any medium, particles in that medium emit and absorb the emitted photons which cause scattering of light.

• Small particles with fine size scatters low wavelength light which is mainly blue light and particles with comparatively larger size scatters larger wavelengths.
• Wavelength of light that is scattered depends on the size of the particles in the medium.

• If particle size is too large, then the scattering caused by it is white. This is because large particles scatters almost all wavelengths of light equally.
