as laser light becomes farther from the source what happens to the area covered with its light will it to widen or stay the same​

Sagot :

Answer:

A narrower beam of laser light spreads out more quickly than a wider beam. Only an infinitely wide beam (a plane wave) does not spread out, and therefore has parallel waves. Divergence is observed by shining a laser light on a wall and then seeing the spot grow bigger as you move away from the wall.
