Question

the speed of sound is certain medium is 960m/s if 3600 waves passes over a certain point in 1 minute the wavelength is

Answer 1

Answer : - 16 m

1 Min = > 3600 waves can pass through the medium

So in 1 sec => 3600 / 60 = 60 waves can pass

velocity = frequency x wavelength

Given that speed of sound is 960 m / s. Substituting in above.

960  = 60 x wavelength

So, wavelength = 16 m

Answer 2

In the event that 3600 waves had ignored a point in one moment, at that point in one sec 60 waves had passed that point  

length of these 60 waves is 960 m  

( speed = recurrence × wavelenght, here number of waves every second is recurrence)  

thus one wavelength is 16 m. so the correct answer to the question is 16m
