# If travelling waves move at 140 m/s on this string, what musical note is this string currently producing?

In hertz

The fundamental is 1/2 wavelength. So you have to know string length.

wavelength*fundamentalfreq= wave speed.

## To determine the frequency of the musical note produced by the string, we can use the formula:

wave speed = wavelength * fundamental frequency

Given that the wave speed is 140 m/s, we need to find the fundamental frequency in hertz.

To calculate the wavelength, we need to know the length of the string. Once we have that information, we can find the fundamental frequency by rearranging the formula:

fundamental frequency = wave speed / wavelength

So, the steps to find the fundamental frequency in hertz would be:

1. Measure the length of the string.
2. Calculate the wavelength by dividing the measured length by 2.
3. Substitute the values of wave speed and wavelength into the formula: fundamental frequency = wave speed / wavelength.
4. Calculate the fundamental frequency using the given values.
5. The resulting value will be the musical note produced by the string in hertz.
