Parts of A Sound Wave

What is the time taken for one complete cycle of a sound wave called?

• frequency

• amplitude

• wavelength

• period

​ (a)   describes the ​ (b)   of waves that pass a ​ (c)   place in a given amount of ​ (d)   . So if the time it takes for a wave to pass is is 1/2 second, the frequency is 2 per second. If it takes 1/100 of an hour, the frequency is 100 per hour.
