Which of the following electromagnetic wave is used in high precision applicatio
Which of the following electromagnetic wave is used in high precision application like LASIK eye surgery?
- A. Microwave
- B. Ultraviolet rays
- C. Gamma rays
- D. X-rays
Step-by-step solution
LASIK eye surgery uses excimer lasers that emit ultraviolet light (specifically at 193 nm) to precisely reshape the cornea, allowing high precision without thermal damage. Microwaves, gamma rays, and X-rays are not used due to their different properties and potential harm.
