Scientists use various instruments to measure speed, such as radar guns, Doppler radar, and stopwatch. Radar guns emit radio waves to measure the speed of moving objects, while Doppler radar uses reflected signals to calculate speed. Stopwatches are used to measure the time it takes for an object to travel a known distance, allowing for the calculation of speed.
The equation used to measure wave speed is: Wave speed = frequency x wavelength
Mach speed.
Velocity is the measure of speed in a certain direction. It is a vector quantity that includes both the speed of an object and the direction in which it is moving.
A commonly used device to measure the speed of a moving body is a speedometer. It measures the instantaneous speed of a vehicle by calculating the rotational speed of the wheels and converting it into a speed reading. Other methods such as radar guns or GPS devices can also be used to measure speed accurately.
A anemometer is used to measure wind speed.
No it is not. Sciencetists say it is not true.

Hertz is a measure of frequency, and has nothing to do with speed problems.Hertz is a measure of frequency, and has nothing to do with speed problems.Hertz is a measure of frequency, and has nothing to do with speed problems.Hertz is a measure of frequency, and has nothing to do with speed problems.
To measure the speed of a wave, you multiply the frequency by the wavelength.
Roemer was the first to measure the speed of light.
Speed is the measure of distance over time.

Speed. Kilometre measure distance, and hour is a measure of time. Distance / Time = Speed.
No. The instrument used to measure wind speed is an anemometer.
