What is a transverse wave?

• when the oscillation/vibration is parallel to the direction of energy transfer

• when the oscillation/vibration is perpendicular to the direction of energy transfer

• when the wave is parallel to the direction of wave travel

• when the wave is at 90 degrees to the direction of wave travel
