why do sun looks reddish while rising and setting.. Give scientific answer...PLZ.....
Answers
At sunrise the earth is rotating towards the sun. Similarly, during sunset, the earth is rotating away from the sun. During these times the sunlight has to travel at an angle and thus cover a longer distance through the atmosphere. It encounters more obstacles in its path. Most of the colours, like green and violet, get scattered before the light reaches the earth. Since red is scattered the least, it is this colour that we see as it reaches us.
During noontime, the sun is directly overhead and it appears white. This is because the sunlight has to cover a much lesser distance through the atmosphere and it faces less obstacles. Hence, it escapes a great deal of scattering.
In fact, if we were to calculate the distance the sun’s rays have to travel through the denser part of the atmosphere (roughly around 150 kms) to any point on earth, we would find that this journey of the rays is almost 50 times more at sunrise and sunset than at noon.
pls mark brainliest if this answer was useful
Here is ur answer......
The red colour in the sky at sunset (and sunrise) is due to an effect called Rayleigh scattering. There is a similar form of scattering called Mie scattering which is responsible for the white colour of clouds.
Particles in our atmosphere that are approximately the same size as the wavelength of visible light cause the white light from the sun to scatter and split into individual components. Oxygen and Nitrogen (the main components of our atmosphere) scatter violet and blue light due to their small size. This is why the sky appears to be blue in the day time, especially at midday when the Sun is closest to us.
During sunrise and sunset the distance that the light has to travel from the Sun to an observer is at its greatest. This means the a large amount of blue and violet light has been scattered so the light that is recieved by an observer is mostly of a longer wavelength and therefore appears to be read.
