Question

sound wave has a wave length 40 m and speed 650m/sec find its frequency​

Answer 1

u search it in google u will get it i am trying my level best ...

Answer 2

wave length = 40m

speed = 650m/s

frequency =?

velocity = frequency x wavelength

frequency =

$\frac{ velocity \: }{wavelength}$

frequency =

$\frac{650}{40}$

frequency = 16.25 Hz

hope it helps you
