X-rays: A Medical Diagnostic Tool

X-rays are a type of electromagnetic wave with a shorter wavelength than visible light. They are used in medical imaging to produce images of the internal structures of the body. X-rays are particularly useful in diagnosing bone fractures, detecting foreign objects in the body, and visualizing internal organs.

The Correct Answer: Luggage Inspections

Given the options provided, the correct answer for the "Use" section for X-rays is B. Luggage inspections. X-rays are commonly used in airport security to inspect luggage for prohibited items, such as explosives or sharp objects. This application is a critical aspect of ensuring public safety and preventing potential threats.

Other Uses of Electromagnetic Waves

While X-rays are primarily used in medical imaging and luggage inspections, other types of electromagnetic waves have various applications. For example:

Radio waves are used in communication, broadcasting, and navigation.
Microwaves are used in cooking and heating food.
Infrared radiation is used in thermal imaging and heating applications.
Visible light is used in illumination and photography.
Ultraviolet radiation is used in disinfection and curing applications.
Gamma rays are used in cancer treatment and sterilization.

Conclusion

In conclusion, electromagnetic waves are a fundamental aspect of our daily lives, with various types of waves having unique properties and applications. X-rays, in particular, are used in medical imaging and luggage inspections. By understanding the uses of electromagnetic waves, we can appreciate the importance of these waves in various fields and their impact on our lives.
