Radar uses electromagnetic waves to find the distance between to points. The speed of electromagnetic waves is the speed of light, 300 Millinmeters/second or 600 Million Nautical Miles per hour or 10 Million Nautical Miles per minute or 6 microsecond per mile..
The distance is r=ct where c is the speed of light. Radar finds the distance by r=c2t, the 2t is ther round trip time of radar. For example it takes light 500 seconds to arrive on earth from the sun. this is about 8 minutes. A radar on earth boucing a signal off the sun would take 16 minutes to bounce back; 8 minutes to get to the sun and 8 minmutes to get back.
Police Radar travels at the same speed but the distances are much smaller but bounce time is still 12 microsecond per mile. So if the bounce time is is 36 microseconds the car is 3 miles away. Using a little algebra the radar can take two hits and figure out how fast your car is moving.
What else can I help you with?
What another term for radar waves?
Another name for radar waves is radar systems or electromagnetic waves.
What electromagnetic waves have the longest wavelength and lowest frequency?
Radio waves have the longest wavelength and lowest frequency among electromagnetic waves. They are used for communication, broadcasting, and radar systems.
What waves that are used in radar?
Radar uses electromagnetic waves, specifically microwaves, to detect and track objects. These waves are emitted by a transmitter and bounce off the target object before being detected by a receiver, allowing for the measurement of the object's distance, speed, and other properties.
Can rhythmic movement of air molecules produce electromagnetic waves?
No, the rhythmic movement of air molecules does not produce electromagnetic waves. Electromagnetic waves are generated by the oscillation of electric and magnetic fields and do not require a medium, such as air, to propagate.
How are sonar and radar different?
Sonar uses sound waves to detect objects underwater, while radar uses radio waves to detect objects in the air or on the ground. Sonar is typically used in marine environments, while radar is commonly used in aviation and meteorology.
Are radar waves electromagnetic waves?
Yes.
What another term for radar waves?
Another name for radar waves is radar systems or electromagnetic waves.
When a police officer uses radar speed for control the officer is using what kind of electromagnetic waves?
Radar uses radio waves.
What type of electromagnetic waves is used in radar?
Radar stands for RAdio Detection And Ranging. So ... radio.
What has the author Alvin Schaffer written?
Alvin Schaffer has written: 'The use of electromagnetic Walsh waves in radar' -- subject(s): Electromagnetic waves
When are no electromagnetic waves produce?
In a vacuum

Which travels faster radar or light?
Radar is accomplished by bouncing radio waves from the target.Radio waves and light are the same phenomenon ... both are electromagnetic waves,and their speeds are equal.
When a police officer uses radar for speed control the officer is using what kind of electromagnetic waves?
radio waves
When the police officer uses radar for speed control the officer is using what kind of electromagnetic waves?
radio waves
Is radar wave mechanical?
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.
