Identify the distance labeled from A to B. Explain what could be done to the note played on an instrument to change that distance. A) B) From A to B is known as the wavelength and changing the pitch of the note will change its length. From A to B is known as the amplitude and changing the loudness of the note will change its length. From A to B is known as the wavelength and changing the amplitude of the note will change its length. From A to B is known as the wave height and changing the amplitude of the note will change its length. D)​
