Sound is a longitudinal wave and a light wave is a transverse wave.

Sound requires a medium to travel through but light can propagate without any medium.

they differ because waves are sound waves and water waves are waves in the water.


Light waves and sound waves differ in many ways one of them being speed. I am going to summarize it in points:-The speed of sound waves in air is almost 360m/s while that of light is 299,792,468m/s. The speed of sound is max in solids.Sound waves are mostly longitudinal. Very few are transversal. Light waves are always transversal.Sound waves are mechanical while light waves are electromagnetic i.e. they have an electric field and an magnetic field in the direction mutually perpendicular to each other.


Light and sound both move in waves. Light is much faster than sound. Light waves are smaller than sound waves.


Sound and water waves are mechanical and therefore need a medium. Light is an electromagnetic wave which travels as a particle-wave, so it does not need a medium to travel through.


Light travels in waves, and sound travels in waves. However, sound waves and light waves are very different, and it is important not to confuse the two. Light travels in electromagnetic waves, and sound does not. Sound waves are caused by vibration.


No because light waves are stronger and brighter and sound waves are light and dull


Sound waves are a type of mechanical waves. Light waves are a type of electromagnetic waves.


Radio and light waves are electromagnetic waves, sound waves are not.


Light has Transverse waves and sound does not.


Sound waves must travel through a medium, light does not require a medium. Sound waves are longitudinal waves, light are transverse waves.


light waves are transversal, seismic waves are longitudinal.


Light waves are transverse.Sound waves may be transverse or longitudinal. Sound in gases can only be longitudinal.


light and sound are in waves, because when a sound is made, such as a gun shot, the sound rips through the air in waves. as for light? noidea bro.


Light waves travel much faster. Also, sound waves are waves of compression that move through matter (usually air, but water and solids work too!). Whereas light waves are part of the electromagnetic spectrum and they do not require anything to move through. They are happy to move through vacuum.


Because sound waves are waves in material media, but light waves are not.


The two are different because Sound waves are longitudinal mechanical waves, but light waves are transverse electromagnetic waves, and sound requires a medium through which to travel, but light doesn't. Basically, Sound waves move sort of differently than Light waves.


Light waves travel faster than sound waves.


Sound waves are much longer then light waves.


Light waves are not mechanical waves. This means that it does not need a material medium as an essential entity to get propagated through. But sound waves need some material medium such as air, water or even solid metals. Water waves badly needs water surface.Light waves has incredible speed but the other two are not so


light waves are a form of light. sound waves are a form of sound. you can hear sound but can not see it.you can see light but you can not hear it.light from a light source such as the sun,a light bulb or flashlight.light is made up of all colors.


Light travels at the same speed for everyone and sound waves do not (necessarily).


of it depend upon the non mechanical waves and the mechanical waves. sound waves are paralell to the motion of the sound it is longitudinal while light waves are transverse



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 meters per second in vacuum. The speed of sound is 343 meters per second in dry air at 20°C.And finally, a simple one - you can see light while you can hear sound.


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.
