The correct option is B A-2, B-3, C-1
Definitions for the given terms:
Tyndal effect: It is the scattering of light as light beam passes through a colloid. The individual suspension particles scatter and reflect light, making the beam visible.
Persistence of vision: When an object is viewed by a person, its image remains on the retina of the eye for a time interval of 0.0625 seconds (116th). If more than one scene is viewed within 0.0625 s, all the images will appear interrelated sponataneously to the eye.
Dispersion: It is the phenomenon of splitting up of a composite light into its constituent colours. The regular array of colours formed by dispersion is the visible spectrum.
