Answer to Question #60361 in Other Physics for Shira

Question #60361
A sonometer wire is stretched over two bridges separated by 1m by hanging a weight W, and it is found that the resulting strain is the wire is 0.25%. if the wire is struck so as to form 2 loops between the two bridges, it makes 4 beats per second with a tuning fork vibrating at a frequency 256Hz. It is found that when the weight W is gradually immersed in water the beat frequency is diminished,
(i) What is the frequency of the transverse waves produced in the wire?
(ii) Calculate the speed of sound in the material of the wave.
