They don't necessarily have a shape.
Sound belongs to the category of mechanical waves, as it requires a medium (such as air, water, or solid material) to propagate. Sound waves are longitudinal waves, meaning they oscillate parallel to the direction of energy transfer.
The visible portion of the ear is shaped in such a way that it best amplifies sound. A pig's ear is large and concave so that it can trap sound waves and amplify them inside the pig's ear for optimum hearing.
Sound waves carry sound
Yes sound does produce waves. These special waves are called sound waves.
sound waves are a example of mechanical waves
Sound waves are longitudinal waves, not transverse waves.
Waves; sound waves.
A megaphone amplifies sound by capturing and directing sound waves through a cone-shaped structure, which increases the volume of the sound. The shape of the megaphone helps to focus and project the sound waves in a specific direction, allowing the sound to travel over long distances without losing much of its intensity.
sound waves dont produce vibrations, vibrations are sound waves.
Waves of sound.
