What is the range in wavelengths for EM waves in the radar bands?

The range of wavelengths for electromagnetic (EM) waves in the radar bands is correctly identified as 1 mm to 1 m. This range covers the microwave segment of the electromagnetic spectrum, which is utilized for radar technology.

Microwaves are essential for various radar applications, including weather observation, air traffic control, and military uses. The wavelengths within this range are particularly effective for detecting objects and precipitation because they can penetrate clouds and perform well in various atmospheric conditions.

The choice that indicates the range of 1 mm to 1 m aligns with the frequencies typically used in radar systems, which can operate at frequencies ranging from about 300 MHz (1 m wavelength) to 300 GHz (1 mm wavelength), giving a comprehensive understanding of how radar technology functions across different atmospheric scenarios.

Other ranges mentioned do not accurately represent the radar bands. For instance, the 0.1 mm to 10 m range is too broad and includes frequencies that extend beyond typical radar applications. Similarly, the ranges that focus on areas such as 1 cm to 1 m might be too narrow, thus excluding critical wavelengths utilized in standard radar systems.
