Question

1. how are sound waves created?

○ tension
○ vibrations
○ amperes
○ electricity

Explanation:

Sound waves are mechanical waves. They are created when an object vibrates. The vibrations cause the surrounding medium (such as air, water, or solids) to vibrate as well. As the medium vibrates, it transfers energy in the form of sound waves. Tension is a force related to stretching, amperes measure electric current, and electricity is a form of energy. None of these directly create sound waves like vibrations do.

Answer:

vibrations
