One violin plays a D-note on the D-string while a second identical violin plays a second D-note on its D-
string. If a resulting beat frequency is produced while both violins play, what can be said causes the beat
frequency?
The tension force is the same on the strings, but the linear mass density is different.
The tension force on both strings is different, and the linear mass density on both strings is equivalent.
The wavelength on the string varies between the two violins.
The amplitude of the string's standing wave varies between the two violins.

A spring lies flat on a frictionless table. One end of the spring is attached to a wall and the other end has a
mass attached to it. The mass is pulled X distance away from the point of equilibrium and released. The
spring oscillates in SHM with a given frequency F. After some time, a second mass of equal weight is added
on top of the original mass. What does not change?
Amplitude
Frequency
Period
Max velocity
