what is the difference between scterring of light and dispersion of light
Answers
Answer:
Explanation: 1.Scattering of light is the phenomenon in which light rays get deviated from its straight path on striking an obstacle like dust or gas molecules, water vapours etc. ... The colors we see in the sky are due to scattering of light.
2.When white light is passed through a glass prism it splits into its spectrum of colours (in order violet, indigo, blue, green, yellow, orange and red) and this process of white light splitting into its constituent colours is termed as dispersion.

Answer:
Dispersion:
White light is primarily composed of light of different wavelengths (colors) viz. violet, indigo, blue, green, yellow and red with red having the highest wavelength while the violet having the lowest wavelength.
Definition
Dispersion is defined as the separation of white light into different colours when the light is passed through the prism. The scattering of light depends on the wavelength of the light. Therefore, it can be said that the degrees of deviation is dependent on the wavelengths. The deviation in the path of the light is inversely proportional to the wavelength.
Description
So when a beam of white light passes through a medium, the material medium splits the white light into different components. This phenomenon is called dispersion.
Splitting of the white light
It is the phenomenon in which white light splits into its constituent colours. White light contains several constituents that vary in their wavelengths (it contains the light of different colours).
Since the wavelengths of these constituents are different, their speeds differ from each other in a medium. Note that their speed in a vacuum is the same.
In a material medium, the speed of different wavelengths is different.
Spectrum
When white light passes through a prism, it disperses into a band of seven different colours. This band of colours obtained from the dispersion of light is called a spectrum. Dispersion of light in a prism results in the formation of a spectrum.
Scattering of light:
When light passes from one medium to any other medium say air, a glass of water then a part of the light is absorbed by particles of the medium preceded by its subsequent radiation in a particular direction. This phenomenon is termed as a scattering of light. The intensity of scattered light depends on the size of the particles and the wavelength of the light.
Definition
Scattering of light can be defined as the deviation of light rays from their straight trajectory. As light propagates through the atmosphere, it travels in a straight path until comes under obstruction from the gas molecules and dust particles in the atmosphere.
