Question

The A note has a frequency of 880 Hz. What is the wavelength if the speed of sound is 343 m/s?

Answer 1

Use v=f∆ where ∆ is lambda
So your v is 343 and your f is 880Hz so solve for lambda in metres because lambda represents wavelength. You can do that maths . 343÷880 is equal to lambda in meters

Answer 2

Answer : The wavelength of the sound is 0.389 m

Explanation :

Formula used :

`\lambda=(c)/(\\u)`

where,

`\lambda` = wavelength of sound = ?

`\\u` = frequency =
`880Hz=880s^(-1)`

c = speed of sound =
`343m/s`

Now put all the given values in the above formula, we get:

`\lambda=(343m/s)/(880s^(-1))`

`\lambda=0.389m`

Therefore, the wavelength of the sound is 0.389 m
