Question

Why laser light is useful?​

Answer 1

Explanation:

Because laser light stays focused and does not spread out much (like a flashlight would), laser beams can travel very long distances. They can also concentrate a lot of energy on a very small area. Lasers have many uses. They are used in precision tools and can cut through diamonds or thick metal.
