Which pair of properties apply to both sound and electromagnetic waves? a) both waves carry energy and refract. b) both waves are longitudinal and carry energy. c) both waves are transverse and need a medium. d) both waves carry energy and do not need a medium to travel through.

A. Both waves carry energy and refract is the correct answer.

Explanation:

A) Both waves carry energy and refract.

Explanation:

Sound waves are longitudinal waves, and electromagnetic waves are transverse waves. So as they are a different type of wave we discard options B and C.

Also sound waves unlike electromagnetic waves, they do need a medium to propagate, which discards option D.

This leads us to the correct option that is A. Both waves carry energy and refract.

All waves are a perturbation that carries energy. Also, refraction occurs in both types of waves, this because both change direction when moving from one medium to another.
