Question

A sine wave has a frequency of 8 Hz. What is its period?
Solution : Since period (7) is the inverse of frequency (/), we have: T=1/f = 1/8=0.125 seconds is the period of the sine wave.​

Answer 1

Explanation:

The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.

The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.Here, a sound wave is vibrating at frequency 50 Hz. Hence, the time period T =  1/f = 1/50 = 0.02 s.

The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.Here, a sound wave is vibrating at frequency 50 Hz. Hence, the time period T =  1/f = 1/50 = 0.02 s.Hence, the sound wave vibrating at frequency 50 Hz has a time period of 0.02 s.
