Explain how:
(i) A guitar note and violin note are being played at the same frequency, however, we can still make out which instrument is producing which note
(ii) Both transverse and longitudinal wave can propagate through solids, but only longitudinal waves can move through gases.

(i) Overtones are produced differently by the guitar and the violin. Even though the notes from a guitar and a violin vibrate at the same frequencies, it is possible to distinguish between them. (fourth) The bulk modulus of elasticity exists in both solids and fluids. As a result, longitudinal waves can pass through them both. Gases, on the other hand, do not have a shear modulus like solids. As a result, transverse waves are unable to penetrate through gases.
