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

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

Solution

Ultraviolet rays are used for sterilizing surgical instruments due to their ability to kill bacteria, microwaves are utilized in radar systems for communication and detection, infrared waves contribute to the greenhouse effect by trapping heat in the atmosphere, and X-rays are essential for studying crystal structures in materials.
