How does tyndall effect help us to see a movie in a theatre?
Tyndall effect is the phenomenon of scattering of light by the particles of a colloid or particles of a fine suspension . In simpler terms when we direct a beam of light towards a colloid or a suspension , its path is visible which is known as TYNDALL EFFECT . It was discovered by John Tyndall.
For e.g. We are able to see a movie in a theatre because of this Tyndall effect. Projector works on this phenomenon. When a movie is run on a projector, it projects itself on the big screen. We are able to see it on the screen due to scattering of light by the dust (colloidal particles) particles present in the theatre.
Hope it helps
