comparing sound and light waves\nwhich statement correctly compares sound and light waves?\nboth light and sound waves need matter to carry energy from one place to another.\nneither light nor sound waves need matter to carry energy from one place to another.\nlight waves carry energy parallel to the motion of the wave, while sound waves carry energy perpendicular to it.\nsound waves carry energy parallel to the motion of the wave, while light waves carry energy perpendicular to it.

Answer

Brief Explanations:

  • Sound waves are longitudinal waves. In longitudinal waves, the particles of the medium vibrate parallel to the direction of wave propagation, so sound waves carry energy parallel to the motion of the wave.
  • Light waves are electromagnetic waves (transverse waves). In transverse waves, the particles of the medium (in this case, no medium is required for light in vacuum, but conceptually) vibrate perpendicular to the direction of wave propagation, so light waves carry energy perpendicular to the motion of the wave.
  • Light waves do not need a medium (matter) to travel (they can travel in vacuum), while sound waves need a medium (matter) to travel.

Answer:

Sound waves carry energy parallel to the motion of the wave, while light waves carry energy perpendicular to it.
