$\text{Hint: Recall the properties of electromagnetic waves.}$ $\text{Explanation: Let's match the items from List I with List II based on the typical uses or properties of different electromagnetic waves:}$ $\text{UV radiations can be focussed into very narrow beams for high-precision applications such as LASIK (Laser-assisted in situ keratomileusis) eye surgery.}$ $\text{UV lamps are used to kill germs in water purifiers. Commonly used for sterilizing surgical instruments because UV rays can kill bacteria and viruses.}$ $\text{Microwaves are used in radar systems for communication and detection purposes.}$ $\text{Due to their short wavelengths of microwaves, they are suitable for the radar systems used in aircraft navigation.}$ $\text{Infrared radiation plays an important role in maintaining the earth’s warmth or average temperature through the greenhouse effect.}$ $\text{Incoming visible light (which passes relatively easily through the atmosphere) is absorbed by the earth’s surface and reradiated as infrared (longer wavelength) radiation.}$ $\text{This radiation is trapped by greenhouse gases such as carbon dioxide and water vapor.}$ $\text{These waves are associated with the greenhouse effect as they are emitted by the Earth and absorbed by greenhouse gases.}$ $\text{X-rays are used to study crystal structures due to their ability to penetrate materials and provide detailed images.}$ $\text{Its analyzes crystal structure through the diffraction pattern.}$ $\text{Therefore the correct match is: (a) \rightarrow (iii), (b) \rightarrow (iv), (c) \rightarrow (ii), (d) \rightarrow (i).}$ $\text{Hence, option (1) is the correct answer.}$
