A string on an instrument (0.9 m long) carries travelling waves at 180 m/s. What are the 3 lowest notes?

Lucious C asked:


A string on a musical instrument (0.9 m long) carries travelling waves at 180 m/s.

a.) What are the three lowest notes that this string can play (keeping the string at its full length)?
lowest:__Hz
second to lowest:__Hz
third to lowest:__Hz

b.) If a note was “fretted”, by reducing the length of the string to 0.225 m, then the lowest frequency note this string could play is:__Hz

c.)What factors determine that the travelling waves on this string will travel at 180 m/s? (select all that apply)
_the tension in the string?
_the wavelength of the note played?
_the thickness of the string?
_the frequency of the note played?

I really apprecite the help!! Thank you!!
