What else can I help you with?
What phenomenon is the basis of police radar and makes light or sound waves increase in frequency if the source is moving toward the observer and decrease if the source is moving away?
The phenomenon is called the Doppler effect. It describes the change in frequency of waves when the source of the waves is moving relative to the observer. In police radar, this effect is used to measure the speed of vehicles by detecting the frequency shift of the waves reflected off the moving vehicle.
What is the term used for the measure of frequency?
The term used for the measure of frequency is "Hertz (Hz)".
How can I measure frequency with a multimeter?
To measure frequency with a multimeter, set the multimeter to the frequency measurement mode. Connect the multimeter's probes to the circuit or signal you want to measure. The multimeter will display the frequency in hertz (Hz) on its screen.

Is the Doppler effect the actual change in a stars frequency of a wave?
No, the Doppler effect is the perceived change in frequency or wavelength of a wave when there is relative motion between the source of the wave and the observer. In the context of stars, the Doppler effect is used to measure their radial velocity, which can be used to determine if the star is moving towards or away from us based on shifts in the wavelength of its light.
What does a droppler measure?
A Doppler measures the change in frequency or wavelength of waves, such as sound or light, as observed by an observer moving relative to the source of those waves. This effect is commonly used in various applications, including radar and medical imaging, to determine the speed of moving objects, such as vehicles or blood flow in the body. The Doppler effect can reveal whether an object is approaching or receding, based on the observed shift in frequency.
If a light source is approaching you at a speed very close to the speed of light it will appear to be what color?
That all depends what color it was when it left the source. Whatever wavelength it had at the source, if it's approaching you, you'll measure a shorter wavelength (higher frequency) as it passes you. But don't forget that regardless of the speed or direction of the source, you'll measure the light passing you at the 'speed of light' ... no more or less.

What is frequency's unit of measure?
Hertz, hz= 1/second is the unit measure of frequency.
What is frequency meter?
frequency meter is used to measure the frequency of unknown frequency signal.

What instrument is used to measure electrical frequency?
Frequency counter
What does kilogram frequency mean?
It is meaningless. A kilogram is a measure of mass. Frequency is a measure of events through time. -firstmate-
