Question

can someone help me with this physics Lab Vibrating String Experiment I'm confused please and thank you

Vibrating String Experiment Objective To study the factors affecting the velocity of waves in a stretched string. Apparatus Linear transducer, function generator, string, meter stick, mass set, table clamp with pulley. Optional: strobe light. Part A Attach one end of a string to the motor and pass the other end of the string over a pulley about 1.5 m away. Set the frequency to 120 Hz. Refer to the figure below to make sure the orientation of the motor is correct. Set the frequency generator amplitude to the 9 o'clock position (about 30% maximum). Do not set the frequency generator amplitude above 30% or else the transducer might drift around the table top. Set the hanging mass to 50 g, and adjust the frequency until you get a 1 wavelength pattern with maximum amplitude. Repeat this procedure, adding 50 grams to the hanger each time, up to a maximum of 300 g. Record the data in the table below. (Note that the masses jump from 200 to 300 in the last trial.)
