A tuning fork is vibrating the air around it. What best describes the waves produced by the tuning fork?
A
mechanical, because the air molecules are moving perpendicular to the tuning forkB
mechanical, because the vibrating tuning fork makes air molecules around it vibrateC
electromagnetic, because the air molecules are moving parallel to the tuning forkD
electromagnetic, because the vibrating tuning fork does not need air in order to produce sound
