What is the wavelength of K-band radar?

The wavelength of K-band radar is 1 1/4 centimeters, which is equivalent to 12.5 millimeters. This band operates in the frequency range of approximately 18 to 27 GHz, and the wavelength is derived from the relationship between the speed of light and frequency, where wavelength is calculated by dividing the speed of light by the frequency.

K-band is significant in radar applications due to its ability to offer a balance between range and resolution. It is widely used in various fields, including automotive radar, law enforcement speed detection, and weather radar operations. The specific wavelength of 1 1/4 centimeters is not only crucial for understanding radar principles but also for ensuring proper operation and calibration of radar equipment.

In contrast, other options represent wavelengths that do not correspond to the K-band. The other choices reflect wavelengths associated with different radar bands. Understanding this distinction helps professionals accurately apply radar technology and interpret the data produced by different radar systems.
