What are the characteristics same for both waves given in the fig (1) and fig (2).
Same: Loudness and Different: Pitch
Same: Quality and Different: Pitch
Same: Loudness as well as Pitch and Different: Intensity
For the above waves, amplitude and frequency are the same. Pitch depends on frequency and amplitude mainly depends on amplitude. So both waves have the same pitch and loudness. Quality/harmonics depends on a waveform. It is different because the waveform is different in both cases.
