Question
Which of the following is a characteristic of sound
waves?Solution
Sound waves are longitudinal, meaning the vibrations move parallel to the direction of the wave. Their speed varies depending on the medium (fastest in solids, slowest in gases). Sound is produced by vibrating objects, transmitting energy through a medium.
