Observed Frequency when Observer Moves towards Source and Source Moves Away Formula Elements

Variables
Frequency Observed
Frequency Observed is the number of oscillations or cycles of a wave that an observer detects per second due to the Doppler Effect.
Symbol: Fo
Measurement: FrequencyUnit: Hz
Note: Value can be positive or negative.
Velocity of Sound
Velocity of Sound is the speed at which sound waves propagate through a medium, affected by the Doppler Effect, resulting in wavelength changes.
Symbol: c
Measurement: SpeedUnit: m/s
Note: Value should be greater than 0.
Velocity Observed
Velocity Observed is the velocity at which the wave is received by the observer, affected by the motion of the source and observer.
Symbol: Vo
Measurement: SpeedUnit: m/s
Note: Value can be positive or negative.
Velocity of Source
Velocity of Source is the speed at which the source of a wave is moving relative to an observer, affecting the wavelength of the emitted wave.
Symbol: Vsource
Measurement: SpeedUnit: m/s
Note: Value can be positive or negative.
Wave Frequency
Wave Frequency is the number of oscillations or cycles of a wave per second, affected by the relative motion of the source and observer.
Symbol: fW
