A simple tuning fork is employed to help students understand more clearly what causes sound and the manner in which sound moves. The vibration of air causes sound to travel from the point of its inception to our ears. This activity allows students to feel vibration using a tuning fork in order to better conceptualize the movement of air around the tuning fork.
- Wavelength - the distance from the top (crest) of one wave to the top (crest) of the next wave
- Frequency - the number of wave cycles/ second
- Hertz - a measure of the number of frequency cycles/ second
- Amplitude - the height of a wave
