Explain polarization by scattering.

Statement-1 : On viewing the clear blue portion of the sky through a Calcite Crystal, the intensity of transmitted light varies as the crystal is rotated. Statement-2 : The light coming from the sky is polarized due to scattering of sun light by particles in the atmoshphere. The scattering is largest for blue light.

The dielectric constant decreases if the temperature is increased .Explain this in term of polarization of the material.

In Rutherford experiments on alpha -ray scattering the number of particles scattered at 90^(0) angle be 28 per minute. Then the number of particles scattered per minute by the same foil, but at 60^(0) is

Explain the scattering of light with an example.

In Rutherford scattering experiment, wha will be the ratio of impact parameter for scattering angles theta_(1)=90^(@) and theta_(2)=120^(@)

Source of alpha -particles used in scattering experiment was

For a wavelength of light and scattering object is size a, all wavelengths are scattered nearly equally, if:

During scattering of light, the amount of scattering is inversely proportional to of wavelength of light

On decreasing the wavelength of incident light from 8000 Å to 4000 Å. The intensity of the scattered light in Rayleigh scattering will become _________ time the initial scattered intensity.
