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.
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
No. As you might guess from the name, radar uses radio waves. Radio waves, in turn, are a type of electromagnetic wave - in other words, in principle similar to light waves.
Using an imaging radar. Also known as Synthetic Aperture Radar (SAR).
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.

Radar waves have a lower frequency that light waves.The frequency of a light wave is related to wavelength and speed by the equation c = »½. The color of a light wave is also determined by the frequency. The amplitude and brightness are not related to the frequency.
Radio waves
Radar uses radio waves, which are a type of electromagnetic energy wave, to detect the presence, direction, distance, and speed of objects.
Yes. The visible spectrum of light is much shorter than the shortest radar (radio) wave.
Radio waves are the electromagnetic waves with longest wavelength.
RADAR = RAdio Detection And RangingRadio waves in the microwave band are used to measure the speed of cars using a technique called "Doppler RADAR", by measuring the change in frequency of the returned waves.These waves are electromagnetic waves.
Radio waves have the longest wavelength among the electromagnetic spectrum, ranging from several meters to kilometers in length.
