A tuning fork vibrating in air produces sound waves. These waves are best classified as
(1) transverse, because the air molecules are vibrating parallel to the direction of wave motion
(2) transverse, because the air molecules are vibrating perpendicular to the direction of wave motion
(3) longitudinal, because the air molecules are vibrating parallel to the direction of wave motion
(4) longitudinal, because the air molecules are vibrating perpendicular to the direction of wave motion
