Sound waves in iron have a speed of about 5100 m/s. If the waves have a frequency of 400 Hz, what is their wave length?

I am thinking it is 12.75
v/f 5100/400 is 12.75 m

Is this correct.
Thank you

correct.

Yes, your calculation is correct. The formula to calculate wavelength is λ = v/f, where λ is the wavelength, v is the velocity of sound waves, and f is the frequency.

In this case, the velocity of sound waves in iron is given as 5100 m/s, and the frequency is given as 400 Hz. Plugging these values into the formula, we get:

λ = 5100 m/s / 400 Hz
= 12.75 m

So the wavelength of the sound waves in iron is indeed 12.75 meters. Well done!

Yes, your calculation is correct. The formula to calculate the wavelength of a wave is:

wavelength = speed / frequency

In this case, the speed of sound waves in iron is given as 5100 m/s, and the frequency is given as 400 Hz.

By substituting these values into the formula, we get:

wavelength = 5100 m/s / 400 Hz
wavelength = 12.75 m

Therefore, the wavelength of the sound waves in iron is indeed 12.75 meters. Well done!
