Match List-I with List-II

Choose the correct answer from the options given below:

(A)-(II), (B)-(IV), (C)-(I), (D)-(III)

The correct answer is Option (3) → (A)-(II), (B)-(IV), (C)-(I), (D)-(III)

• (A) Aircraft navigation — (II) Microwaves: RADAR systems used in aircraft navigation and air traffic control utilize microwaves because their short wavelengths allow them to be reflected by small objects like planes without being easily bent (diffracted) by the atmosphere.

• (B) Cellular phones — (IV) Radio waves: Mobile communication relies on radio waves (specifically in the ultra-high frequency or UHF band) to transmit voice and data signals over long distances through the air.

• (C) Remote switches for TV sets — (I) Infrared waves: Most household remote controls use low-energy infrared LEDs to send coded signals to the receiver on the TV. This is why you usually need a "line of sight" for the remote to work.

• (D) LASIK eye surgery — (III) Ultraviolet rays: Precision medical procedures like LASIK use "Excimer lasers," which emit high-energy ultraviolet light. UV rays are used because they can precisely remove (ablate) microscopic layers of the cornea without damaging the surrounding tissue.
