Answer:
No, it is not correct to say the Doppler Effect is the apparent change in the speed of a wave due to the motion of the source.
Explanation:
While Doppler Effect is due to motion of the source or observer but it is not the apparent change in the speed of the wave. The speed of the wave remains the same. It is the wavelength and frequency of the waves that change in Doppler Effect when there is a relative motion between source and observer.
