Hello!
Let us learn some properties of laser.
Properties of Laser :-
Coherence : The emitter radiation after getting triggered is in phase with incident radiation.
Monochromaticity : The laser beam is highly monochromatic than any other radiations.
Unidirectionality : Laser Bheem travels in only one direction. It can travel long distance without spreading.
Directionality : The light emitted by the laser is highly directional, it focused in a narrow beam.
Focusability : A laser beam can be focus to an extremely find spot.
