Question

if 20 waves pass through the medium in one second with a speed of 20 m per second then the wavelength is​

Answer 1

Answer:

Explanation:

20 waves per second. Frequency is 20/s. Speed is 20m/s. V = wavelength * freq 20m/s = w * 20/s Wavelength = 1 meter.

Answer 2

Given :

20 waves per second (f = 20 Hz)

Speed of 20 m per second (v = 20 m/sec.)

To find :

Wavelength (λ) =  ?

Explanation:

Wave equation :

v = fλ

==>

 20 m/sec. = (20 Hz)(λ)

==>

λ = $20/20$ = 1 meter

hence , the wavelength is​ 1 m
