STANDING WAVE EXPERIMENT 1). If you have the vibrator at a location which causes a standing wave to be visible on the string what do you think would happen if you moved it away or towards the pulley by a distance equal exactly half of the wavelength. Explain 2). Given the equation below, determine the expression for the slope of a graph of tension vs wavelength squared. Start by squaring both sides then rearrange the equation for tension. Include a sketch of the expected graph. 3) Explain why the position of the string vibrator had to be adjusted during the experiment when a new mass was hanged on the string. 4) Give two sources of uncertainty in this experiment and classify them as random or systematic
