Questions  

Two waves are having sinusoidal waveforms have different wavelengths and different amplitude. They will be having (assume frequency same)

a
Same pitch and different intensity
b
Same quality and different intensity
c
Different quality and different intensity
d
Same quality and different pitch

detailed solution

Correct option is A

The pitch depends upon the frequency of the source. As the two waves have different amplitude therefore they are having different intensity. While quality depends on number of harmonics/overtone produced and their relative intensity. Assuming that their frequencies are the same.
