Solution
The correct option is C Tyndall effect
The Tyndall effect is the scattering of light as a light beam passes through a colloid. The individual suspension particles scatter and reflect light, making the beam visible. The amount of scattering depends on the frequency of the light and density of the particles. The angle through which sunlight in the atmosphere is scattered by molecules of the constituent gases varies inversely as the fourth power of the wavelength; blue light will be scattered much more strongly than will the long wavelength red light. The visible beam of headlights in fog is caused by the Tyndall effect. The water droplets scatter the light making the headlight beams visible.
