Question

Calculate the wave length of sound wave whise frequency is 220 hz and dpeed is 440 m/s in a given medium

Answer 1

v=f *lambda
440=220*lambda

440/220= lambda
lambda = 2m

Answer 2

Answer:

Answer:-

Wavelength = 2 A°

• Given:-

Frequency = 220 Hz

Speed = 440 m/s

• To Find:-

Wavelength

• Solution:-

We know the relation,

V=nλ

here,

V = speed of sound wave

n = frequency

λ = Wavelength

Hence,

→ lambdaλ × 220 = 440

→ lambdaλ = 440/220

→ lambdaλ = 2 A°

Therefore, the Wavelength [λ] of sound wave is 2 A°.
