why Sun Appears Red?
Asked by | 07 Jun, 2008, 05:27: PM
Expert Answer
It is due to the different wavelengths of light.
The red light wavelenghts are diffracted the least by the atmosphere. When the sun is setting, the angle of the sun to us becomes more and more shallow, so we see more of the wavelengths that were not diffracted much. This explains why the sun gradually changes from yellow, becoming more and more orange before turning red.
