"Sound waves carry energy parallel to the motion of the wave, while light waves carry energy perpendicular to it." — Option 4.
Explanation: Sound waves are longitudinal mechanical waves (particle vibrations are parallel to the direction of propagation and require a medium). Light waves are transverse electromagnetic waves (the electric and magnetic fields oscillate perpendicular to the direction of propagation and can travel in a vacuum).
