What is the range of frequencies classifying radio waves?

Radio waves are classified within a certain range of frequencies that fall between 3 kHz and 300 GHz. This range encompasses various types of communication technologies, including AM and FM radio, television broadcasts, and mobile communications. The classification is based on the electromagnetic spectrum, where radio waves occupy the lower frequency end, making them suitable for transmission over long distances.

The range specified in the correct choice is significant because it outlines the frequencies that facilitate different forms of wireless communication. For instance, frequencies below 30 MHz are typically used for AM radio broadcasts, while frequencies in the range of 100 MHz to 2.5 GHz are used for FM radio and television broadcasts. Frequencies above 2.5 GHz are used for various modern communication technologies including microwave communication and satellite transmissions.

Understanding the characteristics and applications of this frequency range is crucial for professionals in the field of information systems. It enables the design, implementation, and troubleshooting of communication systems that utilize radio wave technologies.
