Sound waves are caused by vibrations and travel as longitudinal waves which cause by the vibration of the molecules in air (the molecules dont actually move)
Waves; sound waves.
sound waves can't travel in a vacuum (space)
Sound waves require a medium to travel through, and, since space is a vacuum, sound waves can't travel in it.
Sound waves cannot travel through vaccum.
Sound waves travel through a medium, such as air, water, or solids. In air, sound waves create vibrations that travel through molecules in the form of pressure waves. These waves carry the sound energy and allow the sound to be heard by our ears.
Sound travels in longitudinal waves.
sound waves
Sound waves that travel to the ear for hearing are longitudinal waves.
Sound waves cannot travel in space. Sound waves some medium in order to propagate.
Mechanical waves are waves that require a medium in which to travel, i.e., a solid or fluid. As sound needs a medium to travel, sound is a mechanical wave.
Light isanalogous in many ways to sound and many of the equations used to describe sound also apply to light, but there are limitations. Sound waves don't really polarize the way light waves do for example. Light also displays some characteristics of particle behavior that contradict its wave behavior - again making it different from sound.
Sound waves can travel through solids, liquids, and gases.
