Questions
Why is the sky blue?
Air molecules scatter short blue wavelengths much more than red ones (Rayleigh scattering), so blue light reaches your eyes from every direction.
Why are sunsets red and orange?
At sunset light crosses much more air, so most of the blue is scattered away before it reaches you.
What is golden hour?
The warm, low light shortly before sunset (and after sunrise).
