Seeing with sound: Doppler lab

Learning Material  |  Interactive Lesson  |  RAR

Find out how to measure speed and direction by using echo. Transmit a sound at a known frequency and compare it to the frequency of sound waves that bounce back. Send out sounds in a range of media: air, water or steel. Use a formula to calculate the exact speed of a moving object. Notice that if the value is negative, the object is moving away from the observer. This learning object is one in a series of five objects. The series is also packaged as a combined learning object.

Students use a wave model to explain the behavior of sound.
Students use sound frequency values to calculate speed and direction.
Students identify ways in which sound can be utilized.
