Module 6 Doppler Effect
Buzzer

With minimal construction, you can make this twirling buzzer that actively illustrates the wave principle behind the police's speed-trap radar and electronic ocean water current meters. Don't miss the design plans within the Lesson Plans, and the Animations are like nothing else you've seen or heard!

Lesson Plan: Check out this lesson plan that tells you what you need and how to do the demonstration.

Audio: Listen to a real teacher explain techniques to help perform the lab demonstration and how it relates to physical oceanography.

Doppler Effect Animation and HF Radar Animation: Expand your understanding of the Doppler Effect by viewing two animations: the basic physics of the wave pitch change and an example of how HF Radar can work in Alaska.
