Match List-I with List-II List-I (a) UV rays (b) X-rays (c) Microwave (d) Infrared wave List-II (i) Diagnostic tool in medicine (ii) Water purification (iii) Communication, Radar (iv) Improving visibility in foggy days Choose the correct answer from the options given below:

1. (1) (a)-(iii), (b)-(ii), (c)-(i), (d)-(iv)
2. (2) (a)-(ii), (b)-(i), (c)-(iii), (d)-(iv)
3. (3) (a)-(ii), (b)-(iv), (c)-(iii), (d)-(i)
4. (4) (a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)

Correct answer: (4) (a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)

Solution

The correct option matches UV rays with communication and radar, which is incorrect; UV rays are primarily used for sterilization and disinfection. X-rays are indeed a diagnostic tool in medicine, microwaves are used for communication and radar, and infrared waves can improve visibility in foggy conditions.
