If you drew a line from the source of a sound to where you were when you perceived it, it would appear to be a line.
However, upon further analysis (the depth of that depending on the sound you are looking at), you would see that it actually travels in a wave form, having an amplitude, frequency, wave length, period and speed.
Does sound travel in a straight line?
No, sound travels in a wave, therefore it does not travel in a straight line. It does travel in a line, just not a staright one
Sound is a longitudinal wave based on compressions and rarefications of the fluid carrying the sound. These compressions and rarefications travel outwardly from the source in a sphere shape, from the source to the listener is a strait line (radius of the sphere). The wave shape we are so familiar with is the graph of the density of the fluid over time therefore we can still apply all of the wavilinear properties to sound. In short sond does travel in a strait line, sort of.
All shape references would be different if the source is moving... Doppler effect.
Generally speaking, sound leaving a source will travel in all directions, so the answer is yes. The reason behind this has to do with the medium through which the sound is moving. Let's take an example and look at that.
A grandfather clock is sitting in the middle of an empty gym. It is a source of sound, and the ticking can be heard anywhere in that space. The sound of the escapement makes the "clicks" that then travel out from the clock. The reason that the ticking can be heard anywhere in the gym is that that is nothing in there to "block" or "stop" the sound. All the air around the clock "feels" the mechanical energy of the ticking, and all that air carries it outward, and in all directions.
Saying this another way, the mechanical energy of the sound wave will be "spread out" through the air around the clock. There isn't anything to "contain" or "restrict" that energy, and it will move away in all directions. It's similar to waves on a pond. If a pond has a smooth surface, a rock dropped into the water will cause waves to appear. These waves will travel outward in all directions, just as you'd expect. All the water around the point where the rock went in "feels" the mechanical energy. This translates into the wave moving outward in all directions. It's the same with sound.
Sound can have or be given "directionality" in its movement, but diffraction will allow it to "bend" around objects. If someone is using a megaphone in an empty gym and is talking through it, the sound can still be heard anywhere in the gym. It will be louder in front of the megaphone than beside it, just as you'd expect. But sound will still be diffracted around the side of the megaphone. It will still be possible to hear the sounds when standing behind the speaker, even at a distance, because of the diffraction.
Sound waves normally travel in straight lines directly outwards from their source, but they do not always travel in that way. An object standing in the path of a sound wave can affect its movement. When a sound wave hits a hard object, the sound reflects back towards the source in the form of an ECHO.
you can also say it like this, Sound is a longitudinal wave based on compressions and
rarefications of the fluid carrying the sound. These compressions
and rarefications travel outwardly from the source in a sphere
shape, from the source to the listener is a strait line (radius of
the sphere). The wave shape we are so familiar with is the graph of
the density of the fluid over time therefore we can still apply all
of the wavilinear properties to sound. In short sond does travel in
a strait line, sort of.
All shape references would be different if the source is
moving... Doppler effect.
Sound travels in curved lines originating from the original source of the sound sort of like this ^
different mediums have different density so speed of sound will change.hence, the direction of sound wave will change.
It does not. Sound is a wave and its energy dissipates (Spreads) in all directions on the three axes.
seismic waves travel in all directions. the reason we know is because of earthquakes.
Imagine a pool of water. If you dropped a rock in the water you would cause ripples that would travel out evenly in all directions. When one of those ripples hits a wall, you can see that the ripple bounces off the wall. Sound works the same way. Sound is basically just ripples in the air (vibrations). When a sound vibration hits a wall it bounces back much like the ripples in water. * When you hit something and waves travel through the air to your ears. Sometimes sound reflects again.
Sound waves cannot travel through vaccum.
sound is produced by vibration, i.e. when any thing start vibration then it produces sound. for example when a tunnig fork is hit on rubber pad its prongs starts vibration with difinit frequency ad hence produce sound. similarly when the strings of a gittar is dirturbed its starts vibration and hence produces sound. sound required a material medium for their journey, sound can not pass through vaccume because sound waves are mechanical waves.
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 waves, which are mechanical energy, travel in all directions because of diffraction. Diffraction can be thought of as the "bending" of sound waves. To find a more detailed answer to this question, go to the related link listed below. It answers the question perfectly.
sounds travel in all directions caused by vibration of an object.sound can be absorbed by soft fabric.
It depends if its transverse or longitudinal.
Earthquake waves travel in all directions.
Both travel in waves but and come out from all directions if the souce other than that nit very much alike as sound waves are vibrations
Sound travels in all directions. it will spread out.
Rarefactions decompressions travel in the same direction, because sound are longitudinal waves.
Light.
in all directions
Sound and light are both forms of energy that is carried from one place to another.they travel in all directions from the source.
Yes. But it can be focused so that more of it goes in the direction you want it to go. We do that with our mouth, our external ear, speakers, horns, etc.
Up & down, there & back. Aircraft travel in all directions.
