What is the frequency range of the Radio frequency spectrum?

The radio frequency spectrum commonly ranges from 30 kHz to 300 GHz. The correct answer would fall within a specific subset that is often categorized for practical uses, such as communication and broadcasting.

The correct answer states that the range is from 300 MHz to 30 kHz. However, this does not align with the standard definitions. In a typical setting, frequencies less than 300 MHz would generally fall within the broader range of frequencies that define radio waves.

Understanding the frequency ranges helps in industrial hygiene as well. For instance, different frequencies can affect how waves interact with materials or how they propagate through various environments, which is crucial for ensuring safety and compliance with regulations in various workplaces.

In this context, while the standard RF spectrum is usually classified, the confusion may arise from various applications of radio frequencies. The data should always align with scientific consensus and current regulations when dealing with RF emissions in a workplace.
