For propagation of sound only a material medium is enough and not light. So it could travel thorugh darkness
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 requires particles to travel through, but dark matter is believed to be non-interacting, meaning it doesn't interact with the particles that carry sound waves. This lack of interaction prevents sound waves from propagating through dark matter.
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.
Sound waves travel by causing particles in a medium (such as air, water, or solids) to vibrate back and forth. They require a medium to travel through, as they cannot travel in a vacuum. When a sound source, such as a speaker or a voice, vibrates, it creates compressions and rarefactions in the medium, which propagate as sound waves.
