Part 1 Waves on a string with no end

Challenge: Determine the speed of the waves at each tension setting (high, medium and low). Explain what measurements you made to calculate the speed.
Settings: amplitude: 0.75 cm damping: zero

high tension:

medium tension:

low tension:

Does the speed of the wave depend on the frequency or is it the same for all frequencies? Collect data to support your answer: Though wave speed = wave length × frequency, but speed of wave is always change when wavelength of the wave has been changed. Even if frequency will change wavelength will also change keeping speed constant. So speed is not depend on frequency. It is remain same at all frequency.
