Radar comes from Radio Detection and Range. By definition, it uses radio waves.
Ultra sonic waves, very high frequency audio waves, are used in Sonar, the name being analogous to Radar.
Infra Sonic waves are of far too long a wavelength to be useful for any measurement of the distance of the target.
[And there are some technical reasons as well - not dealt with here.]

What is the difference between infrasonic and ultrasonic?
Infrasonic refers to sound waves below the frequency range of human hearing (below 20 Hz), while ultrasonic refers to sound waves above the frequency range of human hearing (above 20,000 Hz). Infrasonic waves are often produced by natural phenomena like earthquakes, while ultrasonic waves are commonly used in medical imaging and pest control.
Where are ultrasonic and infrasonic waves used?
Ultrasonic waves are used in medical imaging techniques like ultrasound scans to visualize internal body structures, as well as in industrial applications for cleaning and welding. Infrasonic waves, on the other hand, are used by animals like elephants and whales for long-distance communication, and can also be generated by natural events like earthquakes.
What are the applications of infrasonic waves?
used for forecasting natural disasters and they are also used in therapeutic devices to treat the people with physical illness :)
How does the wavelength of the waves used in microwaves ovens compare with the wavelength of waves used for radar?
The waves used in microwave ovens have shorter wavelengths (around 12 cm) compared to the waves used in radar systems, which have longer wavelengths (ranging from a few millimeters to several meters). Both microwaves and radar waves are part of the electromagnetic spectrum, but they are utilized in different applications due to their distinct properties.
Why is ultrasonic not used in radar?
ultrasonic waves are not used but radio waves are used in radar technology because ultra sonic waves generally create an image out of the object while we have to confine our study to the geometrical measurements only
What is the difference between ultrasonic and infrasonic sound waves?
Ultrasonic sound waves have frequencies higher than the upper limit of human hearing (20 kHz), while infrasonic sound waves have frequencies lower than the lower limit of human hearing (20 Hz). Ultrasonic waves are used in various applications such as medical imaging and cleaning, while infrasonic waves are produced by natural phenomena like earthquakes and some animal communication.
Waves that are used in radar?
Electromagnetic waves with a wavelength from a mm up to a few cm are used in radar. They will be reflected from a discontinuity in the electromagnet properties of space. e.g. a metal surface.
Infrasonic and ultrasonic sounds?
Infrasonic sounds have frequencies below the range of human hearing (20 Hz or lower), while ultrasonic sounds have frequencies above the range of human hearing (20,000 Hz or higher). These types of sounds are used in various applications, such as communication, wildlife detection, and medical imaging. Infrasonic waves can be felt as vibrations, while ultrasonic waves are often used for their ability to penetrate materials for imaging and communication purposes.
What wave is used in RADAR machines to clock the speed of cars?
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.
What are the applications of infrasonic sound waves?
Infrasonic sound waves have various applications such as in early earthquake detection, monitoring volcanic activity, studying animal communication, and in some musical compositions to create a deep, rumbling effect.
How does the wavelength of waves used in microwave ovens compare with the wavelength of waves used for radar?
The wavelength of waves used in microwave ovens is typically in the range of centimeters, while the wavelength of waves used in radar is typically in the range of centimeters to meters. Radar waves have longer wavelengths compared to the waves used in microwave ovens, allowing them to travel longer distances and penetrate certain materials.
How are radio waves used to detect objects in space?
