MEANING OF WAVELENGTH CHANGE?
FACTORY SETTINGS OF A SIGNAL TRANSMITTER:
Signal speed = frequency x wavelength
We have seen in the book many times that the part of (c + v) in the above Doppler
Equation is the speed of the signal according to the reference system of the signal source.
From the above two equations, we can obtain following equation:
RELATIVE TO SIGNAL SOURCE:
SIGNAL SPEED SENT TO THE MOVING TARGET
Signal speed = Frequency of the transmitter x
