Question

Which is a property of laser light that makes it useful for cutting metals?

A. its focused energy
B. its single color
C. its scattered energy
D.its multiple colors

Answer 1

The answer is A. I hope this helps.

Answer 2

Option A, its focused energy

Step-by-step explanation:

Laser light is unidirectional and thus its energy is focused in one direction only. The laser beam propagates in a starlight line almost like parallel rays with least /no divergence. This allows the energy of the photons with in the laser beam to collect and focus in one direction/or at one specific point only. Along with being directional, these laser beams are coherent and monochromatic.

Hence, considering the basic characteristics of laser beam, option A is the correct answer.
