Type of wave: Transverse; Direction of vibration: Vertically (up and down)
Type of wave: Longitudinal; Direction of vibration: Vertically (up and down)
Type of wave: Transverse; Direction of vibration: Horizontally (left and right)
Type of wave: Longitudinal; Direction of vibration: Horizontally (left and right)
