Question

The wave length of a sound wave whose frequency is 220hz and speed is 660m/s in given medium is

Answer 1

According to the formula

Frequency= speed/wavelength

Wavelength=660/220

Wavelength=3m

I hope this helps (θ‿θ)

Answer 2

Solution :

⏭ Given:

✏ Frequency of sound wave = 220Hz

✏ Speed of sound wave = 660mps

⏭ To Find:

✏ Wavelength of sound wave

⏭ Concept:

✏ Frequency is defind as ratio of velocity to the wavelength.

⏭ Formula:

✏ Formula of frequency is given by

$\star \: \underline{ \boxed{ \bold{ \sf{ \pink{frequency = \dfrac{velocity}{wavelength}}}}}} \: \star$

⏭ Calculation:

$\implies \sf \: \red{ \lambda = \dfrac{v}{ \nu} } \\ \\ \implies \sf \: \lambda = \dfrac{660}{220} \\ \\ \implies \underline{ \boxed{ \bold{ \sf{ \large{ \purple{ \lambda = 3m}}}}}} \: \gray{ \bigstar}$
