The length of a guitar's strings is 650 mm. What is therefore the wavelength of a wave on any of the strings if the string is free to move?

Answer 1

1.3 m

Step-by-step explanation:

The wavelength of a wave generated by the string of a guitar, if the string is free to move, is twice the length of the string, that is:

`\lambda=2L`

L: length of the string = 650mm

By replacing you calculate the wavelength and obtain:

`\lambda=2(650mm)=1300mm=1.3m`

hence, the wavelength is 1.3 m
