Question

A sound wave with a frequency of 400 Hz is moving through a solid object. If the wavelength of the sound wave is 8 m, what is the speed of sound traveling through the solid object?

Answer 1

v = 3200 m/s

Step-by-step explanation:

As we know that the frequency of the sound wave is given as

`f = 400 Hz`

wavelength of the sound wave is given as

`\lambda = 8 m`

so now we have

`speed = wavelength * frequency`

so we will have

`v = (8m) * (400 Hz)`

`v = 3200 m/s`
