Which of the following statements is not true for the scattering of light?
- Colour of the scattered light depends on the size of particles of the atmosphere.
- Red light is least scattered in the atmosphere.
- Scattering of light takes place as various colours of white light travel with different speeds in air.
- The fine particles in the atmospheric air scatter the blue light more strongly than red. So the scattered blue light enters our eyes.
