Conceptual Doppler Effect Objectives Measure the detector frequency for waves emitted from a slowly moving source as that source is approaching the detector. (Exploration 1) Calculate the detector frequency for waves emitted from a slowly moving source as that source is moving away from the detector. (Exploration 2) Sketch the wave-front patterns for wave sources with various source speeds. (Exploration 3) Description of Activity In this activity, you will study waves that travel from a moving source to a detector. You will control the source speed as well as the frequency of waves emitted by that source. You will observe the wave fronts and measure the frequency at the detector. The Jump Start exercises below will help you review frequency, wavelength, pitch, and the Doppler effect. Jump Start 1. What type of wave is a sound wave? sound waves are compression waves, or longitudinal waves 2. Define wave frequency. The number of waves passing a fixed point in a specified period of time 3. What is pitch? The quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone. 4.
