Question

Calculate the wavelength of a sound wave whose frequency is 220 Hz and speed is 440 m/s in a given medium.​

Answer 1

Answer:-

Wavelength = 2 A°

• Given:-

Frequency = 220 Hz

Speed = 440 m/s

• To Find:-

Wavelength

• Solution:-

We know the relation,

$\large\boxed{\sf\green{V = n \lambda}}$

here,

V = speed of sound wave

n = frequency

λ = Wavelength

Hence,

→ $\lambda$ × 220 = 440

→ $\lambda$ = 440/220

→ $\lambda$ = 2 A°

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

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,

→ λ × 220 = 440

→ λ = 440/220

→ λ = 2 A°

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