In the given figure:
Name one characteristic which is the same and another characteristic which is different for the sound produced by the waveforms. Given in the fig (1) and fig (2).
Same: Loudness as well as Pitch and Different: Quality
i) Same: Pitch, loudness because the amplitude and frequency of both the waves is same.
ii) Different: Quality / harmonics because the waveform is different in both the cases.
