The diagram below depicts :
Figure: a repeating sine-like wave plotted against time (in seconds) on the horizontal axis; the vertical extent is marked 'amplitude', the distance between two successive peaks is marked 'period', the top of a wave is labelled 'crest' and the bottom is labelled 'trough'.
Show answerHide answer
Correct answer: (A) Sound in wave form.
Explanation
The figure shows a wave with amplitude, period, crest and trough plotted against time, which is how a sound wave is represented.
