A piano wire 50 cm long has a total mass of 10 g and its stretched with a tension of 800 N. Find the frequency of the wire when it sounds its third overtone note.

The pitch of a musical note is determined by the frequency of the sound wave that it produces. If two instruments have the same frequency, which of the following factors will most affect the difference in their pitches?

A sonometer's fundamental note is 50Hz, what is the new frequency when the tension is four times the original?

The fourth overtone of a closed pipes is 900Hz, its fundamental frequency is 

Two tuning forks of frequencies 6Hz and 4Hz respectively are sounded together. The beat frequency is
