Question

What is the wavelength of a sound wave that has a speed of 340 m/s and a frequency of 880 hz? what is the wavelength of a sound wave that has a speed of 250 m/s and a frequency of 400 hz? what is the wave speed of a wave that has a frequency of 50 hz and a wavelength of 2.0 m? what is the wave speed of a wave that has a frequency of 100 hz and a wavelength of 0.50 m?

Answer 1

The Answer is 0.773

Step-by-step explanation:

Answer 2

To get the answer first you need to utilize the equation below:

v = fλ

since the problem is looking for the wavelength, then we need to change the equation:

λ = v/f

λ = 340
`(m)/(s)` / 440 s
`^(-1)`

λ = 0.773m

Therefore the sound wave has a wavelength of 0.773m.
