How Doppler Effect Became Effective In Modern Science?
The Doppler effect is a phenomenon observed in waves, such as sound or light, when there is relative motion between the source of the wave and the observer. It causes a change in the frequency or wavelength of the wave, resulting in a perceived shift in pitch or color. When the source and the observer move closer together, the waves appear compressed, leading to a higher frequency or shorter wavelength, and vice versa. This effect is commonly experienced with passing sirens of emergency vehicles or when observing the redshift of distant galaxies in astronomy. The Doppler effect has practical applications in various fields, including radar technology, medical imaging, and astronomy.
