Q: What is the type of wave that travels in the same direction as that of the disturbance?
A: The type of wave that travels in the same direction as that of the disturbance is called a longitudinal wave.
Q: In what direction does a wave transfer energy?
A: A wave transfers energy in the direction that it is moving.
Q: What is longitudinal and transverse wave?
A: A longitudinal wave is a wave in which the particles of the medium vibrate in a direction parallel to the direction of propagation of the wave.
A transverse wave is a wave in which the particles of the medium vibrate in a direction perpendicular to the direction of propagation of the wave.
