1. Doppler effect is a phenomenon where the frequency of a wave appears to change when the source of the wave is moving relative to the observer.
2. It is named after Christian Doppler, an Austrian physicist, who first described the effect in 1842.
3. The Doppler effect is commonly observed in sound waves, where it causes the pitch of the sound to appear higher or lower depending on the motion of the source relative to the observer.
4. It is also observed in electromagnetic waves, such as light waves, where it causes a shift in the color of light emitted by a moving object.
5. The Doppler effect is used in a variety of applications, from determining the speed and direction of moving objects to measuring blood flow in medical imaging.
