Physics
Two musical notes of the same pitch and same loudness are played on two different instruments. Their wave patterns are as shown in figure.
How do they differ in:
(a) Loudness
(b) Pitch and
(c) Quality?
Answer
(a) Loudness will be same for both the instruments because they have same amplitude.
(b) Pitch will be same for both the instruments as they have same frequencies.
(c) Quality will be different as they have different wave forms as seen in the diagram of the given wave patterns.
