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.
