​

Answer 1

Sound waves are fundamentally from the other waves.

Explanation:

• A sound wave is an arrangement of disturbance caused by the flow of energy traveling through a medium.

• The medium can be air, water, liquid, or any other solid matter, whereas electromagnetic waves do not need any medium to propagate.

• Radio waves, light waves, and X-rays are electromagnetic waves.

• Electromagnetic waves are a combination of electric waves and magnetic waves.
