a) A string 1.75 cm long under tension is set in vibration so that five antidotes are produced. What is the wavelength of the vibration?
b) A cord of mass 200grams and length 2.5m is stretched between two supports 2.2 meters apart and given a tension of 678N.
I)How long will it take for a pulse to travel from one support to the other?
ii) What are the first three resonant frequency will the string produce if struck?
C) By what percentage should the tension on a stretched string on unknown length and mass be adjusted for the fundamental frequency to change by 10%?
