Melde’s experiment is ideal to study the behavior of standing waves. Students can even visually determine wavelength, period and amplitude of waves.
A string undergoing transverse vibration illustrates many features common to all vibrating acoustic systems just like the vibrations of a violin or guitar string.
we may determine the frequency of tuning fork by using this experiment
yes
time was not calculated at the right point so the poits of the graph were chaned
SO that the oil cup gets uniformly heated from all the sides
pulleys allow you to lift significantly more weight than without them
steel is one of the most important engineering materials on earth
When doing a controlled experiment, you get accurate results.

because this is the right place to do an experiment
Gives you a more correct method of predicting which is the right one.
You need a control for any experiment. It doesn't sound like this particular experiment is of the utmost importance but it's a good habit to get into if you plan more important ones. I have no idea what the control would be.
The string in Meldes experiment can be made to vibrate in several ways. In most schoolphysics experiments the devices are: 1) loudspeakertype vibrator, where a rod is connected to a loudspeakermembrane and transmits the oscillations to a wire mounted on the end of the rod. 2) small DC-motor with an arm attached to the rotor. The string is attached to the arm, which moves up and down 3) electrical vibrator with coils and vibrating metalblade. The string is attached to the metalblade. In each case the device is driven by a signal-generator that outputs a harmonic electric signal.
Depending on the size/importance of the experiment, they can either simply repeat as normal or if needed gather more resources for the experiments. Scientists always perform experiments at least three times, to make sure nothing is abnormal in an experiment.
