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.

What type of energy wave is used with the radar?
Radar uses radio waves, which are a type of electromagnetic energy wave, to detect the presence, direction, distance, and speed of objects.
What is the length of full wave?
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.
A speed and length of a wave decrease the wave does what?
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.
How the Doppler effect is used by the police to measure the speed of a car.?
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.
What is the relationship between length and wave frequency?
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.
What is a wave-length?
A wavelength is the length between the crests (the top of the waves). This picture shows a good example: http://www.bom.gov.au/weather/radar/about/images/wavelength.gif
What is radar wave length?
Assuming you mean the wavelength: Radar can use electromagnetic waves of VERY different frequencies; see this section of "Radar" in Wikipedia: https://en.wikipedia.org/wiki/Radar#Frequency_bandsThe list also includes the corresponding wavelengths; or you can divide the speed of light by the frequency.

How do satellites see through clouds?
Using an imaging radar. Also known as Synthetic Aperture Radar (SAR).
What is the form of electromagnetic wave from radar system?
Microwaves.
What does radar do?
Radar sends out a radio wave and measures the reflected radio wave using it to calculate a target's speed, shape, material the object is made of, and direction of movement.
What happenes to the wave when you decrease the wave length?
When you shorten the wave length, you increase the amplitude.
What type of electromagnetic wave used in radar?
Radar stands for RAdio Detection And Ranging. So ... radio.
Cw radar vs cw radar?
CW in reference to radar usually means Continuous Wave. (CW Radar = Continuous Wave Radar) I don't think that it is usually referred to in a case sensitive way. You will need to explain the context better. Continuous Wave Radar references a radar system in which the transmitter is never turned off. The target illuminating, radio frequency emitter power is non-stop and unbroken. Isolation between the transmitter and receiver has to be specially considered during design.
What are the different Types of radar?
radars are of two types pulsed and continuous wave radar. pulsed radar has its carrier pulse modulated used for detecting stationary objects continuous radar uses direct sine wave for transmitting and is used for moving targets there are types such as weather, and aircraft.
