Write the applications of scattering of light at day time.
Answers
The scattering of light at During day
time the colour of sky is blue because light coming from the Sun hits the molecules present in the Earth's atmosphere and scatters off in all possible directions.
* Among all colours (VIBGYOR), blue
colour scatters most because it has a
shortest wavelength which lies in
range of visible spectrum.
* During night, the part of Earth is faces
away from the Sun and the space
looks black because there is no any
bright source of light that get
scattered by atmosphere of our Earth.
The applications of scattering of light at day time are as follows:
1. The blue colour of sky during daytime is due to scattering of blue light more than red by the particles present in the air.
2. The appearance of red or orange sky during sunrise as well as sunset. This occurs due to the scattering out of the blue light.
Also the appearance of the red colour of sun during sunrise or sunset is based on this.
3. The blue colour of water as observed in water bodies is also the result of selective absorption of light and its scattering.
