What type of electromagnetic wave is used for radar?
It is microwaves that are used for radar. They are high frequency, short wavelength electromagnetic waves, and a number of different frequency ranges of these microwaves are used depending on the application. A link is provided to the Wikipedia article on radar and the different bands or ranges of frequencies that are used and their applications.
Give 5 differences between radar and sonar?
SONAR stands for Sound Detection and ranging, and RADAR stands for Radio Aid to Detection and Ranging. as described below (by richard), the principle is simple. Point a signal source in one direction, Listen for the echo to return, and time how long the return signal took, Divide it in two, and with some math, and knowing the speed of the wave, work out how far away the object is. Now if you make the sender/receiver directional. you can move it left and right, and see how wide the object is. If you can rotate it 360 degrees, you get a map of what is arround you. (Gavin)BY sending out a hi frequency pulse to an aircraft and detecting the timing for the return it can be calculate the speed and direction basically location of an aircraft. Sonar has the same principle applied timing of a response return PING to detect the location.Radar is a system that uses radio electromagnetic waves to provide a range to a target normal in air or a vacuum. RADAR propagates its radio waves at the speed of light. Sonar uses sound and propagates in pressure wave through water and the speed of sound. And provides a range to a target in a similar way, just at slow speed.
What did the radar do?
radar sends electromagnetic waves and it is reflected back by the object such as a plane or a sub and based on the analysis of time and speed of wave we get the position of object. for an example of radar they used radar before pearl harbor and saw many planes, the radar operatiors thought it was a squadron of b-29's returning to base but it ended up being the empire of japan's zero's (type of lightly armored plane that sacrificed armor for speed,agility,and a better service ceiling (how high a plane can go))
What is the principle of radar?
The basic idea behind radar is very simple: a signal is transmitted, it bounces off an object and it is later received by some type of receiver. This is like the type of thing that happens when sound echo's off a wall. However radars don't use sound as a signal. Instead they use certain kinds of electromagnetic waves called radio waves and microwaves. This is where the name RADAR comes from (Radio Detection And Ranging). Sound is used as a signal to detect objects in devices called SONAR (Sound Navigation Ranging).
Why can aluminium jam radar?
Radar waves can pass through many substances (they appear transparent like glass) but are reflected efficiently by metals (which act more like a mirror to radar). Thus if you want to confuse a radar system you can scatter a mass of thin, light aluminium confetti in the air and this will appear as a fog, hiding the target (your plane) from the enemy. Aluminium is used because it is a light metal that can be made into thin sheets or ribbons (aluminium foil).
What another term for radar waves?
Another name for radar waves is radar systems or electromagnetic waves.
What is a palindrome for detection system using radar waves?
"Radar detection system: madam rotor" is a palindrome for detection system using radar waves.
Are radar waves electromagnetic waves?
Yes.
What kind of waves are in radar detectors?
Radio waves.
Which waves have lower frequency radar waves or visible waves?
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.
Which rays does radar use?
Radar uses radio waves for detecting and tracking objects. These radio waves are emitted by the radar system and bounce off nearby objects, with the reflected waves then being detected by the radar receiver to determine the object's location and speed.
What amplitude and frequency does a radar waves have?
Frequency is above 1 GHz or so for radar. General amplitude of waves put out by a radar gun is what I was trying to find when I stumbled across this. I imagine its in the mV or lower range though
Do radar waves require a medium?
No.
When a police officer uses radar speed for control the officer is using what kind of electromagnetic waves?
Radar uses radio waves.
What are micro waves dangers?
yes
What are the dangers of gamma waves?
radiation
What is a palindrome transmitting radio waves?
radar
