A laser beam is used for carrying out surgery, because it

• A. is highly monochromatic
• B. is highly coherent
• C. is highly directional
• D. can be sharply focused

Answer 1

The correct option is D

can be sharply focused

While using technical equipments for medical purposes we need to use a device which should ease out the process of diagnosis and treatment and at the same time it should be more efficient than the manual treatment. In surgery, a laser beam can provide us a sharp focus at the area to be operated, which makes easy for doctors to carry out the surgery effectively.
