Measuring the Doppler Effect EXPERIMENTAL PROCEDURES & QUESTIONS Tutorial: The Doppler Effect ( ) If either the source or the receiver of a wave is in motion the apparent wavelength and frequency of the received wave change. This is apparent shift in frequency of a moving source or observer is called the Doppler Effect . The speed of the wave is not affected by the motion of the source or receiver and neither is the amplitude. This simulation looks at the Doppler effect for sound; the black circle is the source and the red circle is the receiver. The time is measured in centiseconds (10 -2 s), distances are in meters. The speed of sound is 345 m/s. A similar effect occurs for light (speed = 3 × 10 8 m/s) but in that case the source and receiver cannot travel faster than the wave speed (the speed of light).
