Speed Gun, Applications and Working Process

About Speed Gun

• It is a device to measure the speed of a moving object without having to be in contact with the object.
• It uses electromagnetic radiation, typically radio waves, which bounce off the object to calculate its speed using the Doppler effect.

Applications

• Traffic monitoring by law enforcement.
• Sports for tracking athlete performance.
• Industrial uses requiring precise motion tracking.

How did Speed Guns work?

• Speed guns emit radio waves, which are reflected by the moving object.
• The frequency difference between the emitted and reflected waves is used to determine the speed of the object.
• The speed is calculated using the formula: (frequency difference * speed of light) / (2 * emitted frequency).
• The speed of light in a medium is constant, allowing for accurate speed measurement over long distances.
