Have a leader say "go" to start the sound wave. Have the children try striking the tuning fork and then touching the water.

The oscillogram for this call looks like this: Each peep looks like a burst of sound signal (loudness) separated by spaces of very low signal (quiet). We call this back and forth motion a cycle. As a mechanical wave, sound requires a medium. Wave: The continuous transfer of energy by vibrating the medium of propagation is called wave. The less time it takes the air molecules to oscillate back and forth, the higher note that we perceive.

Wave speed is literally how fast the wave moves from one location to another. The nature of sound waves answer key figures. Thankfully, waves are good at bouncing off walls and bending around objects and gaps. The speed of sound in air increases with temperature.
When we hear something, we are sensing the vibrations in the air. At one end, have a child squeeze and then release a few of the rings.

Interaural phase difference — phase differences. C. It is the perceived quality of a musical note, sound, or tone. Decibel (dB) - a unit of measurement that represents the logarithmic ratio between a sound wave's highest and lowest pressure.

The nature of sound | Sound: A Very Short Introduction | Oxford Academic.
