Radio Waves

Radio waves are a type of electromagnetic radiation with wavelengths longer than infrared light. They are used for various forms of communication, including radio and television broadcasting, cell phones, and wireless internet.

Properties of Radio Waves

• They have the longest wavelengths in the electromagnetic spectrum.
• They have the lowest frequencies in the electromagnetic spectrum.
• They can be easily diffracted and reflected, allowing them to travel long distances and around obstacles.
• They are used for long-distance communication because they can travel through the Earth's atmosphere and interact with the ionosphere.

Uses of Radio Waves

Radio waves are used for a variety of purposes, including:

• Radio and television broadcasting
• Cellular communication
• Wireless internet
• Radar systems for navigation and weather forecasting
• Remote controls for electronic devices
