MCQ
Two waves having sinusoidal waveforms have different wavelengths and different amplitude. They will be having
  • ✓
    Same pitch and different intensity
  • B
    Same quality and different intensity
  • C
    Different quality and different intensity
  • D
    Same quality and different pitch
✓

Answer

Correct option: A.
Same pitch and different intensity
a
(a) The pitch depends upon the frequency of the source.

As the two waves have different amplitude therefore they having different intensity.

While quality depends on number of harmonics$/$overtone produced and their relative intensity.

Assuming that their frequencies are the same.
