(c) A test CD for use in a music studio contains a series of pure tones (musical notes) that can be used for testing audio equipment. One of these tones is selected and played through a loudspeaker, producing a constant sound of a specific frequency. One of the strings on a guitar in the same room resonates with this sound, forming a standing wave. The string vibrates in its third harmonic mode.
(i) Sketch the string's vibration, clearly labelling the nodes.
(ii) The length of the string is 0.630 m and the speed of sound in the string is 425 ms. Calculate the frequency of the string's vibration (and hence of the original sound).
please solve this with in 30 minuts
