Question

A wave travel through a distance of 60cm in 3 seconds the different between successive crest on the wave is 4cm calculate the frequency of the wave

Answer 1

Answer:

velocity=distance/time

=60/3=20cm/s

as distance b/w two crest is 4 cm wavelength = 4cm

we know

v=f×wavelength

f=20/4

f=5 Hertz

PLEASE MARK AS BRAINLIEST

Answer 2

Explanation:

v=d/t

v=60/3

v=20cm/s

given:wavelength = 4cm

therefore,

v=f×wavelength

20=f×4

f=5hz
