A wave travels a distance of 20cm in 3seconds.if the distance two successive crest is 4cm. Calculate the frequency

1 answer

The speed of the wave can be found by dividing the distance traveled (20cm) by the time taken (3s):

Speed = distance/time = 20cm/3s = 6.67 cm/s

The frequency of the wave can be found using the formula:

Frequency = Speed/Wavelength

where wavelength is the distance between two successive crests (4cm in this case).

Frequency = 6.67 cm/s รท 4cm = 1.67 Hz

Therefore, the frequency of the wave is 1.67 Hz.
