Solution

The correct option is B Same pitch and different intensity
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 a number of harmonics/overtone produced and their relative intensity. Assuming that their frequencies are the same.

Q. Two musical notes of the same frequency and same amplitude are played on two different instruments. Their wave patterns are as shown below.

How do they differ in (a) loudness (b) pitch and (c) quality?

A man $X$ can hear only upto 10 kHz and another man $Y$ upto 20 kHz. A note of frequency 500 Hz is produced before them from a stretched string. Then

how do you account for the fact that two string can be used to give note for the same pitch and loudness but of different quality.
