What is the scattering of light? How are we able to see
objects when the light is turned on?
Answers
Answer:
Scattering is the phenomenon in which light ray is redirected in different directions on passing through particles of dimensions comparable to the wavelength of the light.
Due to atmospheric scattering, blue light is scattered the most while red light is scattered the least.
During day, red light is not scattered as the light travels lesser distance and scattering of blue light by the atmosphere makes it appear blue.
During sunrise/sunset, when the Sun is near the horizon, sunlight has to travel a larger distance and blue light is scattered away. Since the red light is scattered less, it can travel longer distances and hence, sun appears reddish during sunrise/sunset.
Answer:
Let's explore the scattering of light with the help of an experiment. When we shine a laser through a glass of water with few drops of milk, we can see the path of light. This effect is often called the Tyndall effect
