A source of waves produces 20 crests and 20 troughs in 0.4 seconds. Find the frequency of the wave.

Asked by Sakshi

Answer (2)

1 whole wave is 1 crest and 1 trough.
20 crests and 20 troughs is 20 whole waves.
20 waves / 0.4 seconds = 50 waves per second.
Frequency = 50 Hz

The frequency of the wave is calculated by dividing the number of complete waves produced (20) by the time taken (0.4 seconds), resulting in a frequency of 50 Hz. This indicates that 50 wave cycles occur every second. Therefore, the frequency is 50 Hz.
