Answer :
Well, Harry, what you said is not necessarily true the way you said it.
But we know what you mean, and what you meant to say is true.
The Doppler effect is observed if there is relative radial motion
between an object and an observer AND if the object happens
to be putting out sound or light in the observer's direction.
The statement," If an object stays still, but the observer moves, the Doppler Effect is still observed" is true and satisfy the condition of Doppler Effect.
A system of source of sound waves and observer, such that there is variation in the frequency of sound due to the motion of either source or the observer. Then such variation of frequency is determined using the Doppler Effect.
In general, Doppler effect is defined as the apparent difference between the frequency of source of sound moving relative to the observer or vice versa. So, the application of Doppler's effect is easily noticed with a moving source and stationary observer. Hence, the Doppler's effect is still observed if an object stays still, but the observer moves.
So, the statement is true.
Thus, we can conclude that the statement," If an object stays still, but the observer moves, the Doppler Effect is still observed" is true and satisfy the condition of Doppler Effect.
