A laser beam is used for carrying our surgery because it

A

is highly monochromatic

B

is highly coherent

C

can be sharply focussed

D

is highly directional

Text Solution

Verified by Experts

The correct Answer is:
C
LASER is the short form of light Amplification by Stimultaded Emission of Radiation. It is a device by which an intense, monochromatic,collimated and highly coherent light beam can be obtained . Laser beam is used in surgery because it can be sharply focussed.
