Why does the Sun appear white at noon?​

Answer 1

Answer:

At noon we know that the sun is overhead and when the sun is overhead , it has less air to travel through. We also know that scattering occurs due to dust and other suspended particles in air . So, scattering is reduced if the distance to be travelled in air is reduced. That's the reason sun appears white at noon.
