In the arrangement shown in the figure below, a mass M is bung from a thing that passes over a pulley linear density (mass per nod length) of the string is 0.002 kg/m. The vibrator has a single frequency of 120 Hz. The mass M is adjusted to generate various standing wave patterns.

For the pattern showy in the figure, the "loop" light nest to the vibrator is not sanded as a real) Therefore in this pattern the inmate, of real loops is n = 5.

(a). (0.5 point) If the distance D is measured to be 80cm, calculate the wavelength of this pane

(b). Calculate the speed of wave in this pattern

(c). Calculate the tension in the string for this gallon.

(d). Find the hanging mass M for this pattern.

Imagine that you want to generate another standing wave pattern with only 3 real loops on the setup. Compared to the pattern with 5 real loops, the new pattern with 3 real loops.

(e). has a .....................longer ......or ...............shorter (choose one) ....................... wavelength: (f). has a .....................larger ........or................ soldier ..............................................wave speed;

( Note : In this setup, when mass M varies, the tension in the string varies and therefore the wave speed varies.)

(g). has a ......................larger...................or...................smaller...............tension to the string

(h). needs a .............................larger................. or............... smaller............. hanging mass M.
