Lasers emit light of a certain frequency in one, precise direction. The light that a laser emits can be tuned to have a high frequency and energy. Lasers that emit high-energy light are often used

b. as scalpels in surgical procedures.

Explanation:

Lasers are useful in clinicals for soft tissue surgery. It is used to cut, ablate, vaporize, and coagulate. There are several different laser wavelengths used in soft tissue surgery. Different laser wavelengths and device settings (such as pulse duration and power) produce different effects on the tissue.

It focuses a narrow beam and creates high-intensity light. This function; ability to focus very accurately on tiny areas, they can be used for very precise surgical work or for cutting through tissue (in place of a scalpel).
