    • Tennis ball or wiffle ball (something you can cut open)
    • Knife (not shown)
    • A 9-volt battery and connector
    • A 9-volt buzzer (a high-pitched one works best)
    • Scrap paper to pack inside the ball (not shown)
    • Heavy rubber bands or tape (not shown)
    • Strong string
    • Optional: On/off switch (available at hardware stores)

    What is the Doppler effect and how does it work?
    With the "Doppler shift", the sound pitch of an object moving toward your location is higher due to compression (a change in the phase) of sound waves. As an object moves away from your location, sound waves are stretched resulting in a lower frequency. You have probably heard this effect from an emergency vehicle or train.
    What is the Doppler effect and what is it used for?
    What is the Doppler effect used for? Doppler effect is used to measure speed in RADAR sensors. When the fixed-frequency radio wave sent from the sender continuously strikes an object that is moving towards or away from the sender, the frequency of the reflected radio wave will be changed.

    How can a person observe the Doppler effect?
    The Doppler effect is observed whenever the source of waves is moving relative to an observer. The Doppler effect can be described as the effect produced by a moving source of waves in which there is an apparent upward shift in frequency for observers towards whom the source is approaching and an apparent downward shift in frequency for observers from whom the source is receding.
