## What is Rayleigh law of scattering?

According to Rayleigh scattering law, the amount of scattering of the light is inversely proportional to the fourth power of the wavelength. From the relation between scattering and wavelength, we understand that shorter wavelengths scatter more. Since blue light has a lesser wavelength than red light it scatters more.

Which light scatters the most?

Red color scatters the most since it has the smallest wavelength.

### Is Rayleigh scattering refraction?

Index of Refraction (n): When light is transmitted through a material, each photon travels at the speed of light, c. However, Rayleigh scattering causes the transmitted wave to be out of phase with the free-space (initial) wave. The light is scattered many times as it travels through the medium.

What is Rayleigh formula?

The eigenvalue relation (Rayleigh, 1894) is. c 2 = ( 1 – 2 α ) 2 – e – 4 α 4 α 2 .

#### Does green scatters more than yellow?

The incoming sunlight is white, a mixture of all the colors. Air molecules don’t scatter all the colors equally, they scatter the shorter wavelengths (violet blue green) in greater amounts than the longer wavelengths (yellow orange red). This is depicted above.

Why do red light scatters least?

When light enters the atmosphere, it is scattered by small air particles. The scattering of light is inversely proportional to the fourth power of its wavelength. As the red light has the highest wavelength among all the colours in the visible light, it is scattered the least.

## What is Rayleigh scattering in radiation?

Rayleigh scattering, dispersion of electromagnetic radiation by particles that have a radius less than approximately 1/10 the wavelength of the radiation. The process has been named in honour of Lord Rayleigh, who in 1871 published a paper describing this phenomenon.

Is Rayleigh scattering isotropic?

It is known that in case particles having size less than one-tenth the wavelength of light, Rayleigh scattering occurs and the scattering is isotropic. But for particles whose sizes are comparable to the wavelength of light, the scattering is more towards the forward direction and hence is anisotropic.
