🤓🤓Welcome to pg17 physics class!
- It is a phenomena called Rayleigh scattering.
- (White) Light from the sun is made up of spectrum of colours (think rainbow).
- Each coloured light has its own wavelength
- If I recall correctly, the longest wavelength are in the red area and the shortest in the blue, violet etc area.
- When light from sunlight enters our atmosphere it collides with the oxygen and nitrogen atoms.
- Most of the longer wavelengths pass straight through as little of the red, orange and yellow light is affected by the air.
- However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Hence the sky looks blue.
