When the wire of sitar is plucked what type of wave is produced in the wire and in the air?

When the wire of a sitar is plucked, it produces a transverse wave in the wire. This is because the displacement of the wire occurs perpendicular to the direction of the wave's propagation. In the air, the sound wave generated is a longitudinal wave, where the air particles vibrate parallel to the direction of the wave's travel, creating compressions and rarefactions that propagate sound.
