It depends on the frequency; The equation for wavelength is 300/frequency in megahertz. A radio emitting energy at 30MHz is producing waves 10 meters long.
But since radars usually work up in the SHF and EHF spectra, the wavelengths are measured in centimeters or millimeters. An example: You are a cop who catches speeders with a K-band radar. It, like every other K-band radar, emits at 24.150GHz, or 24,150MHz. So...using that equation, you will find the wavelength is 1.2 centimeters.

Radar waves have varying wavelengths depending on the type of radar system being used. Common radar systems operate within the frequency range of about 1 cm to 1 meter, corresponding to wavelengths ranging from millimeters to meters. The specific wavelength used for radar applications is determined by factors such as the desired range, resolution, and atmospheric conditions.
Radar uses radio waves, which are a type of electromagnetic energy wave, to detect the presence, direction, distance, and speed of objects.
The length of a full wave is determined by the wavelength, which is the distance between two consecutive peaks or troughs of a wave. The length of a full wave is half of the wavelength.
If the speed and length of a wave decrease, the frequency of the wave will also decrease. This means the wave will have a lower pitch or tone.
Police use radar technology to measure the speed of a car by sending out a radio wave towards the vehicle. The radio wave bounces off the car and returns to the radar unit. The Doppler effect causes a shift in the frequency of the returning wave, allowing the radar unit to calculate the speed of the car based on this frequency shift.
In general, the relationship between length and wave frequency is inversely proportional. This means that as the length of a wave increases, its frequency decreases. Conversely, if the length of a wave decreases, its frequency increases.
