Two strings (string A and string B) are set up on a benchtop alongside each other. Each string has two bridges along its length the same distance apart. The
two strings have equal tension. A nearby loudspeaker produces sound at 440 Hz.
String A shows three nodes between the bridges, string B shows two nodes
between the bridges.
Calculate µA/µB where µA and µB are the linear mass densities of string*A*and*string*B.
