Question

find the wavelength when wave velocity is 340m/s and frequency is 20-KHz​

Answer 1

Wavelength=velocity/frequency

Hence.. 340/20= 17m.

Answer 2

wave velocity:- 340m/s

frequency :- 20000Hz

wavelength :- x

V=lambda×frequency

340=x × 20000Hz

x=340/20000

x=0.017

:. wavelength=0.017
