Question

The low notes on a piano always produce ________ sound waves than the high notes.

a) longer

b) lower-amplitude

c) shorter

d) higher-amplitude

Answer 1

Low notes on a piano produce longer sound waves with lower frequencies compared to the high notes, as lower frequencies result in lower pitches.

Step-by-step explanation:

The low notes on a piano produce longer sound waves than the high notes. This is because the frequency of the sound wave determines the pitch of the sound; lower frequencies result in lower pitches. The size of the instrument also influences the pitch it produces. Smaller instruments, like a piccolo, tend to produce shorter wavelengths with higher frequencies, resulting in higher pitches. Conversely, larger instruments, such as a piano when playing low notes, generate longer wavelengths with lower frequencies, and hence, lower pitches. It's important to note that amplitude correlates to volume, not pitch, so louder sounds have higher amplitudes but not necessarily higher frequencies.
