Question
A mass is hung from the end of a string with
linear density 1.5 g/m around a small fric-
tionless peg. For some values of this mass the
string resonates with the vibrator's frequency
and develops visible standing waves. A vibra-
tor of constant frequency 258 Hz is attached
near one end of the string. The vibrating
length of the string is 2 m.
