Doppler effect is the change in frequency or wavelength of a wave, such as sound or light, due to the relative motion between the source of the wave and the observer. The effect was first described by Austrian physicist Christian Doppler in 1842.
The phenomenon occurs when the source of the wave is moving towards or away from the observer. When the source is moving towards the observer, the waves are compressed, resulting in an increase in frequency and a higher pitch for sound waves or a shift towards the blue end of the spectrum for light waves. Conversely, when the source is moving away from the observer, the waves are elongated, resulting in a decrease in frequency and a lower pitch for sound waves or a shift towards the red end of the spectrum for light waves.
Doppler effect is commonly observed in everyday life. For example, the change in pitch of a car horn as it approaches and then passes by a stationary observer, or the change in pitch of an ambulance siren as it moves towards and away from an observer.
Doppler effect has many practical applications in science and technology. For instance, it is used in weather radar to detect the velocity and direction of raindrops, in medical ultrasound imaging to visualize blood flow and heart function, and in astronomy to measure the speed and distance of stars and galaxies.
In conclusion, Doppler effect is a fundamental concept that describes the change in frequency or wavelength of a wave caused by the relative motion between the source of the wave and the observer. It has numerous applications across various fields of science and technology.
