sound is a vibration of particles heard by the eardrum, light is a photon (a particle) that flies around and bumps off things. Why? well that is one of the universal, unanswerable questions
sound
No. Light travels at about 875 thousand times the speed of sound.
light and sound have to be generated from an object! Although light can travel through space with no air, sound can not as it needs something to travel through.You are able to shoot a gun in space and it will not be heard!
Light waves are eletromagnetic waves and sound waves are mechanical waves. Additionally, a light wave is a transverse wave that does not require a medium through which to travel. Sound waves, on the other hand, are longitudinal waves where the source transfers the mechanical energy of the sound wave into the medium so it can travel.
The differences between light and sound are as follows:Light can be considered to be made of waves as well as particles. Sound is only a wave. It does not show particle nature.Light waves are electromagnetic waves while sound waves are mechanical waves.Light waves are transverse while sound waves are longitudinal.Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum.The speed of light in a medium is constant. The velocity of sound waves can change.In sound waves, the particles of the medium actually oscillate. In a light wave, the electric and magnetic vectors oscillate.Light waves can be polarized, but sound waves cannot.Light waves travel much faster than sound waves. The speed of light is a physical constant. Its value is exactly 299,792,458 metres per second in vacuuum. The speed of sound is 343 metres per second in dry air at 20°C.And finally, a simple one - you can see light while you can hear sound.
Both light and sound can indeed travel through glass. These are substances in which light and sound often travel through.
sound can travel in vaccum but light cannot travel in vaccum
light can travel through a vacuum whereas sound cant
Light can. Sound can't.
Both light and sound travel. Light travels the fastest.
sound and light can travel through sound air solids water liquids light wiers lightbubs extentions etc.
light can but sound cant as there is no air
no from what i have learned light travels faster then sound
Light travels much faster than sound, through wood.
no, light is faster
it is sound that requires a medium to travel .. light is an electromagnetic wave ..it doesn't require a medium..
No, it does not. It can travel through any open space. Sound, unlike light, needs a medium to travel. So light can travel through outer space but sound cannot because there is no medium.
