In what year did John Tyndall discover the scattering of light by atmospheric particles?

  • 1869

  • 1889

  • 1909

  • 1929

Answer

John Tyndall discovered the scattering of light by atmospheric particles in 1869. He found that when a beam of light passes through a cloud of particles, the beam is scattered in all directions. The amount of scattering depends on the size of the particles and the wavelength of the light. This discovery helped to explain why the sky is blue and why the sun appears red at sunrise and sunset.
