Web31 mrt. 2024 · The Doppler effect, or shift, was named after Christian Doppler, who first discovered it in 1842. The Doppler effect is the change in wavelength of light, radiation or sound from a source due to its relative motion. In the same way, the sound waves from a receding police car sound as though they have a lower frequency. Web2 dagen geleden · This apparent change in the pitch (or frequency) of sound is called Doppler shift. Light from distant stars and galaxies can be shifted in much the same way. Like sound, light is a wave that can be described in terms of its frequency, the number of wave peaks that pass by each second.
