A string stretched out between two fixed posts is set vibrating by a mechanical oscillator attached to one end. (1) The string is oscillating in a standing wave with 5 loops, then sketch the standing wave and label all nodes (N) andantinodes (A). (2) The frequency illustrated in #1 249 Hz. Calculate the frequency you'd have to set the oscillator to in order to decrease one loop from the standing wave. (3) The string is L = 3.08 m long. Calculate the wavelength of the standing wave you sketched in #1. (4) Calculate the speed v of the waves on the string. (5) The string's mass is m = 4.79 g. Calculate the magnitude of the string's tension. Watch units! (6) In #2 you calculated the oscillator frequency that would remove one loop from the standing wave. Should you increase or decrease the string tension,then, to add another loop to the standing wave? Explain in 1-2 sentences. (7) Calculate the tension that will add one more loop to the standing wave at the frequency chosen in #2. The string's linear density = m/L remains constant.
