Because otherwise we wouldn't hear the sound if we were above or below the source of the sound. Only if we were at the exactsame height.
It heads out in every direction possible.
Because we live in a 3 spacial dimensional universe, it would be a circle in a 2D universe.
Sound waves cannot travel through vaccum.
there is no air in a vaccum. and sound needs air for the sound waves to travel through.
Sound (and vibration) are a wave system of sequential compressions and rarefactions of a material. These waves are mechanical and do need a substance through which to travel. They cannot travel through a vacuum.
Sound is a pressure wave. Objects that "allow" sound to travel through them could be called wave guides.
Spongy materials are the most difficult for sound to travel through. Vacuum is the best acoustic insulation but it doesn't really count for the purpose of this question, since it is not a material but a lack of material.
Sound travels in all directions from the point of its creation, spreading out in a spherical pattern. It does not travel in a single angle but rather in a 360-degree pattern.
Yes sound waves are longitudinal, rather than transverse, the oscillate parallel to the direction of travel
Because they are unconstrained. That is, the ripples on the water surface are constrained to be on the surface of the water by their very nature: that is, a ripple is by definition a disturbance on the surface of the water. Since the surface of the water is flat, then the ripples cannot be spherical and they must instead assume the 2D intersection of the sphere which is commonly known as a "circle. " In fact, "sound" waves can travel through water and these are distinct from ripples. Like their airborne counterparts, subsurface sound waves also propagate spherically -- they travel in 3 dimensions because they can and they are not constrained by anything to propagate in merely 2 D.
Sound requires a medium to travel
Sound can travel on the moon because there is no atmosphere. Space is a vacuum that does not allow sound to travel.
Sound wave do not travel through vaccum as it need medium to travel.
sound needs a material medium to travel. Sound can travel by compression and rarefactions.attma
Yes, sound is a wave and it travels when there is a medium for it to travel through.
An atmosphere. Sound cannot travel in a vacuum.
sound waves can't travel in a vacuum (space)
Sound can travel through:airwaterrocksoil
Sound waves require a medium to travel through, and, since space is a vacuum, sound waves can't travel in it.
