Question

1.Hold one end of a meter stick down firmly on a table so that 20 centimeters of the meter stick extends past the edge of the table. Pluck the end of the meter stick that extends past the table to produce a vibration and a sound as shown. Observe the vibration and sound of the meter stick.

2: Do the same thing but at 40 centimeters this time. Observe the vibration and sound.
3: This time at 60 centimeters. Observe the vibration and sound.

Answer 1

I have done this assignment before so I can tell you the more length that hangs over the table, the less vibration there is due to lack of tension.
