It is typically measured between two easily identifiable points, such as two adjacent crests or troughs in a waveform. It is named after the Austrian physicist Christian Doppler, who described the phenomenon in 1842.. A common example of Doppler shift is the change of pitch heard when a vehicle sounding a horn approaches and recedes from an observer. For electromagnetic waves, the wavelength determines the type (radio, infrared, visible, ultraviolet, x-Ray, gamma – ray) of radiation, in the case of visible light, wavelength determines the colour of the light.
