Doppler Demo
Specification:
Doppler Demo -Everyone has heard a car engine change in pitch when it roars by. Bring
this effect into the classroom with our new kit. In effect, it's a
buzzer on a string which, when swung like a pendulum, emits sounds of
differing ptiches depending upon whether the pendulum is rising or
falling.
