Laser
Laser explained in an easy to understand way:
Imagine trying to get a group of people at a crowded party to focus on singing the same song at the same time. This is similar to how a laser works, where it aligns countless light waves to move together in perfect harmony. Just as you need everyone to synchronize their voices and sing in unison to produce a clear and focused song, a laser organizes light waves of a single color and frequency into a tight, directed beam, ensuring they all "sing" the same "note," creating a powerful and precise output.
