Question

Which statement correctly compares sound and light waves?
Both light and sound waves need matter to carry energy from one place to another.
Neither light nor sound waves need matter to carry energy from one place to another.
Light waves cany energy parallel to the motion of the wave, while sound waves carry energy perpendicular to it.
Sound waves camy energy parallel to the motion of the wave, while light waves carry energy perpendicular to it.

Answer 1

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

Explanation: Both of light and sound travel by waves. Sound waves carry on energy in a material medium but light waves travel in vacuum ( which means no matter exists  in it ). Sound waves oscillate parallel to the direction of propagation. All electromagnetic waves are transverse, which means travel perpendicular to the direction of propagation.

Answer 2

Answer:

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