Look at the diagrams. Which diagram best illustrates transverse waves and why?
Diagram A because the direction of vibration is the same as the direction of motion of the wave energy.
Diagram B because the direction of vibration is the same as the direction of motion of the wave energy.
Diagram A because the direction of vibration is perpendicular to the direction of motion of the wave energy.
Diagram B because the direction of vibration is perpendicular to the direction of motion of the wave energy.
