Two musical notes of the same pitch and loudness are played on a violin and a piano. The waveforms are as shown in the figures below. Explain why the wave patterns are different.

(N/A) Even though the two musical notes have the same pitch (frequency) and loudness (amplitude),they sound different because of their different 'quality' or 'timbre'.
This difference in quality arises because the number and nature of the harmonics and overtones produced by the violin and the piano are different.
Each musical instrument produces a unique combination of harmonics and overtones along with the fundamental frequency,which results in the distinct wave patterns observed for each instrument.
