Unformatted text preview: of the Doppler EFect. Aim 1: How does our perception of a wave change when its source moves towards us or away from us? Aim 2: How is a sonic boom formed? 3 The Doppler Efect The frequency we hear or see depends on the relative motion of us and the source . Examples: 1. Mosquito flying past you : sounds higher pitched approaching. sounds lower pitched leaving. 2. Sonic Booms : sonic and supersonic flight. 3. Red ShiFt and Blue ShiFt in the Cosmos : • Galaxies appear redder than expected. Why do you think this is so? • Some stars appear redder on one side and bluer on the other. Why do you think this is so? 4...
