Question

Frequency of a sound wave is 20Hz. Find out its wavelength. (speed of sound in air =340m/s)​

Answer 1

Answer:

Using the well known relation between wavelength frequency and velocity of a wave,

V =νλ

20

340

> λ>

20000

340

Thus,

λ=[0.017,17] in meters

Explanation:

THANKS

Answer 2

Answer:

17m

Explanation:

Wavelength=Speed of sound/Frequency

=340/20=17m
