What do we call the distance labeled from a to b and what could we do to the note played on an instrument to change that distance?
a) from a to b is known as the wavelength and changing the pitch of the note will change its length.
b) from a to b is known as the amplitude and changing the loudness of the note will change its length.
c) from a to b is known as the wavelength and changing the amplitude of the note will change its length.
d) from a to b is known as the wave height and changing the amplitude of the note will change its length.
