Question:
A nylon guitar string has a linear mass density of 
and is under tension of 
.
The fixed supports are are 
apart. The string is vibrating
in the standing wave pattern shown in Fig.32 (3 antinodes).
Calculate
Solution:
The wave speed can be computed from the relation 
.
From the diagram, we see that 
, which gives
.
The frequency is therefore 
, 
.
