The period of a sound wave is 0.002 seconds. the speed of sound is 344 m/s. whats the frequency

= 500 Hz

Explanation:

A Period of a wave is the time taken for one complete oscillations by the wave particles. It is measured in seconds.

Frequency on the other hand is the number of complete oscillations covered by a wave in one second. It is measured in Hertz.

Period is the inverse of frequency.

That is; Period, T = 1/ frequency, f

T = 1/f and thus; f = 1/T

Therefore;

f = 1/0.002 seconds

 = 500 Hz

the answer would be c. motion and direction
