the seriosly obviose one- one is for light the othe is for sound, if you dont know which is which then you need some help.....

Sound and light are waves, so they have wavelength, frequency, etc. Differences aren't many. Light has higher frequency i.e., 1014 . Sound has 105 Lights frequency corresponds to its color. But Light waves and sound waves are different in many ways.. Light waves are electromagnetic in nature while sound waves are not. Light waves travel as energy as well as particle. But sound travels only as particles. Light wave has two components (electrical and magnetic). Sound doesn't. Light waves travel in straight lines. Sound waves doesn't..... and so on

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&Acirc;&deg;C.And finally, a simple one - you can see light while you can hear sound.

There are two main differences between sound waves and light waves. The first difference is invelocity. Sound waves travel through air at the speed of approximately 1,100 feet per second; light wavestravel through air and empty space at a speed of approximately 186,000 miles per second. The seconddifference is that sound is composed of longitudinal waves (alternate compressions and expansions ofmatter) and light is composed of transverse waves in an electromagnetic field.

Speed of sound is 343 m/s at 20 degrees Celsius or 68 degrees Fahrenheit. Speed of light is 299792458 m/s in vacuum. Scroll down to related links and look at "Acoustic or sound waves in air and radio and light waves in a vacuum".

sound waves are created by things that make sounds like sombody speaking or instruments. water waves are created by wind.

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

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, sound waves are not light waves. The two are completely different.Sound waves are longitudinal mechanical waves, while light waves are transverse electromagnetic waves, and sound requires a medium through which to travel, but light does not.A brief outline of key differences between light waves and sound waves:Sound requires a medium (gas, liquid, air) to travel through. Light does not.Light can also be treated as a particle, sound cannot.How you calculate the energy of a sound, or light wave is also different. Light energy is related to the frequency (or wavelength, these two values are closely related) - "E=hf". The energy of a sound wave is related to it's amplitude (|a|2)and frequency.The speed of sound is relative to the speed of the observer, while the speed of light is constant, regardless of the speed of the observer.Sound is a pressure wave, a region of higher and lower densities in a material, moving through the material. Light is an oscillation in the strength of electrical and magnetic fields moving through space.They are different types of waves, sound is a compression or longitudinal wave, light is a transverse wave.

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 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.

A wave is simply something vibrating or oscillating. Water waves are when the surface of a body of water moves up and down, seismic waves are when the earth vibrates, sound waves are when the air vibrates (this is what your ears detect) and light is caused by vibrations in the electromagnetic spectrum - the same thing as radio waves, microwaves and gamma waves.

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

Probably the most fundamental difference between light waves and sound waves is that light is electromagnetic energy, while sound is mechanical energy. Additionally, sound waves are longitudinal and light waves are transverse waves. Lastly, light waves do not require a medium through which to travel. Sound waves, because the mechanical energy from the source is transferred into the medium, actually must have something to move through to carry the mechanical energy of the wave.------------------------------------------------------------sound waves are vibrating air molecules that transfer energy which we hear as sound, different frequencies are heard a different notes.light waves are wavelengths of electromagnetic energy some of which are visible to the human eye, different frequencies are seen as different colors on the color spectrum.-------------------------------------------------------------------------Light waves are not mechanical waves where as sound waves are mechanical waves.Mechanical waves need a material medium to get propagated.Light waves could also be considered as photons but sound waves have to be considered as phonons.A Light waves' velocity is 300,000 km per sec, while a sound wave will travel at a velocity of 330 m/s in air.----------------------------------------------------------------sound wavesthey need a medium for travellingspeed of sound waves is less than light wavesound cannot travel in spacelight wavesthey do not need a medium for travelling.speed of light is more than sound waves.they can travel in space

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.

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.
