FAQ

What is the Doppler Frequency?
Doppler frequency refers to the frequency shift that occurs in a wave, such as sound waves, light waves, due to the relative motion between the source of the wave and the observer. Doppler Frequency is usually measured using the Hertz for Frequency. Note that the value of Doppler Frequency is always positive.
Can the Doppler Frequency be negative?
No, the Doppler Frequency, measured in Frequency cannot be negative.
What unit is used to measure Doppler Frequency?
Doppler Frequency is usually measured using the Hertz[Hz] for Frequency. Petahertz[Hz], Terahertz[Hz], Gigahertz[Hz] are the few other units in which Doppler Frequency can be measured.
