The sun is less bright at morning and evening as compared to at noon although its distance from the observer is almost the sam.e Why?
Answers
Yes sun looks more brighter in noon than morning or at night because during noon, the sun rays fall directly on the earth's surface. The sun being a yellow star, it's rays also appear yellow at noon. Since yellow has a relative high relative luminosity, it produces a high sensation of visibility in our eyes that causes the sun look to more brighter.
The sun is less bright at morning and evening as compared to at noon although its distance from the observer is almost the same because, blue light is more diffused than red light.
Explanation:
The deeper the sun sets into the sky, the more sunlight must pass through the atmosphere to pass through us.
The atmosphere is a thin layer on the ground (compared to the diameter of the earth).
When the sun shines through the atmosphere, part of the light is absorbed or scattered.
Blue light is more diffused than red light, so that the sun not only looks weaker, but also red when the sun approaches the horizon.
