Lasers are used for precision tasks like aiming weapons or scanning bar codes because ____.
A) they generate a large amount of energy
B) they can be treated as any other type of light
C) the beam is not adversely affected by its travel
D) it is monochromatic

Question

Quizplus · Accepted Answer

Lasers produce a very focused and stable beam of light, meaning it will not scatter or become distorted over long distances. This makes it ideal for precision tasks like aiming weapons or scanning bar codes, where accuracy is key. Additionally, lasers are monochromatic, meaning they produce a single color or wavelength of light, which also contributes to their precision.
