When the time of Evening and Morning ,  Why Sun look red in colour?

We all know that the earth revolves around the sun. The sun takes longer in the morning and the sun takes longer to reach the earth. But the time for the sun to reach the earth at midday is fifty times more than the time for sunshine in the morning and evening.

                                                         Dust, smoke, water and particles in the atmosphere scatter the colours of yellow, orange, and red in the sun. Of these three colors, red will dominate another two colours . And yellow and orange light rays  will disappear when it enters into Earth’s atmosphere .

In this way , we can see only red colour .This is the reason , why  the sun looks red when it rises in the morning and in the evening.
