What is the wavelength of X band radar?

The wavelength of X band radar is identified as approximately 3 centimeters. This classification is based on the electromagnetic spectrum, where X band typically refers to the frequency range from 8.0 to 12.0 gigahertz (GHz). The relationship between frequency and wavelength is governed by the formula: wavelength = speed of light (in meters per second) divided by frequency (in hertz).

Using this formula, we can calculate that at a frequency of around 10 GHz, the wavelength would indeed be about 3 centimeters. This range is commonly used in various applications, including radar and communication systems, making it a well-defined part of the microwave section of the spectrum. Understanding this wavelength is crucial for professionals working with radar technology since it influences radar performance, including detection range and resolution.

Other options do not fall within the correct wavelength range associated with X band radar, as they either correspond to different radar bands or do not reflect the standard definitions used in the industry.
