D/w dispersipn and scatterimg of light
Answers
Answer:
SCATTERING MEANS CHANGE IN THE DIRECTION OF LIGHT WHEN IT STRIKES A PARTICLE .PHENOMENON SUCH AS BLUISH COLOR OF SKY,OCEAN AND REDDISH APPEARANCE OF SUN IS DUE TO SCATTERING OF LIGHT.
ON THE OTHER HAND,DISPERSION MEANS SPLITTING OF WHITE LIGHT INTO ITS SEVEN COMPONENT COLOURS.EG Dispersion of white light on passing through a prism to form VIBGYOR .
Answer:
Dispersion:
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.
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.
Scattering of light:
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. The process in which light gets deflected by the tiny particles in the medium through which the light passes is called scattering.
