Scattering OF Light

Blue colour of the sky is due to a. Adsorption of light by dust particles b. Reflection of light by dust particles c. Scattering of light by dust particles d. Pressure of clouds which are a colloidal dispersion of water particles in air

When sunlight is scattered by atmospheric atoms and molecules the amount of scattering of light of wavelength 880 nm is A. Then the , the amount of scattering of light of wavelength 330 nm is approximately

Statements : The blue colur of sky is due to scattering of light by dirt or dust particles oresebt ub aur . Expabnations : Larger size of disperes phase particles show more sctteing as well as higher is the wavelength of light lesser is scattgering .

When white light is passed through a colloidal solution containing fine suspended particles of gold, then the scattering light seen in a direction different form that of incident light is:

Assertion : The blue colour of sky is on account of scattering of sun light. Reason : The intensity of scattered light varies inversely as the & fourth power of wavelength of the light.

Assertion: Sky appears blue colour. Reason: Colloidal particles of dust scatter blue light.

If the ratio of amounts of scattering of two light waves is 1:4, the ratio of their wavelength is
