✔ 最佳答案

I just think that the quality of note X and the quality of note Y are not the same, since the shape of two waves are totally different
不同的發音體產生不同的波形，而形成不同的音品。(quality of note)

This picture shows two instruments with same quality of note
(1) is true
(2) is false, since the frequency of two waves are the same
(3) is true, since the amplitude of wave X is larger than wave Y
