When particles scattering light are smaller than its wavelength, the amount of scattering is proportional to 1 / λ 4 . Does this mean there is more scattering for small λ than large How does this relate to the fact that the sky is blue?

To determine

The reason for to pass some light through two perfect polarizing filter with perpendicular axes when a third polarizing filter is placed between them and the circumstances under which most of light pass.

Explanation

Introduction:

The Rayleigh scattering occurs when the particles causing the scattering are smaller in size than the wavelengths of radiation in contact with them.

Rayleigh scattering depends on the wavelength of light as,

Rayleighscattering1λ4

Thus, as the wavelength decreases, the amount of scattering increases
