Doppler Effect in class 11 chapter 14 waves refers to the variation in the wavelength or frequency of a wave in relation to an observer moving relative to the wave source. When the wave source moves toward the observer, the frequency increases, and waves are compressed. If the source moves away, the frequency reduces and the waves are stretched. The Doppler Effect can be observed with the sound of a passing train or ambulance. This concept is also used in medical imaging technologies like Doppler ultrasound, radar, and astronomy to find whether galaxies or stars are moving away or towards the Earth.
