Experiment -3

Using the same thickness of wire, try lengths of 15 cm sticking out of the polystyrene block, but use different sizes of plasticine balls.
Try three at a time and compare them.

Hint ! If you can't tell the difference, then make the largest ball a bit bigger and the smallest one smaller until you can.

Which ball of plasticine has the lowest natural frequency? (Answer)

Take the balls and wires out of the polystyrene block and pull the wires out of the balls.
