Perbandingan antara gelombang melintang dan gelombang membujur:
Comparison between transverse wave and longitudinal wave:

Gelombang melintang Gelombang membujur
Transverse waves Longitudinal waves

Gelombang melintang ialah gelombang di mana Gelombang membujur ialah gelombang yang mana

Takrif berserenjang dengan arah perambatan gelombang. selari dengan arah perambatan gelombang.
Definition Transverse waves are waves in which the direction Longitudinal waves are waves in which the direction
of vibration of the particles of the medium is of vibration of the particles of the medium is
perpendicular to the direction of wave propagation. parallel to the direction of wave propagation.
