Why does light travel faster than sound? what is making the sound move slower?

Question

why cant i choose best answer

Answer 1

light is a electro-magnetic wave in which the magnetic and electric fields causes generation of one other and they are not transversal waves, also they can travel in a medium and without a medium( in vaccum or space) ie our radio signals, light waves ettc..

but on other hand the sound waves require a medium to travel, indeed the sound energy propagates by a kind of disturbance that is produced when molecules viberating in their normal frequencies start to viberate with more displacement and this causes collision and transfer of energy to neighbouring molecules and the continuity of the process restricts the speed with which this disturbance is travelling.

so it low in speed.

Answer 2

As was pointed out sound waves are vibrating matter converted to electrical impulses in the ear. Sound travels approximatly 770 miles per hour at sea level. The density of the medium in which sound (vibrations) travels has a large affect on its speed. More dense media tend to have sound travel faster. Light is electromagnetic radiation of a certain fequency and can travel 186.282 miles a second in a vacuum. Light actually slows down cosiderably when passing through a clear substance, this is what causes refraction and is the principal behind magnifying glasses and eyeglasses.

Light is a particle called a photon. This particle can travel whether or not there is air (or anything else it can travel through). Sound on the other hand is a vibration. As the sound wave hits something like a particle of air, that bumps and vibrated the thing next to it and so on and so forth until it gets to our ears. Sound travels at the speed that it does because the particles of air are not tightly packed together. If they were we could not walk through it. It takes a bit for the vibration to travel. Sounds can travel faster in more tightly packed materials (density) and so a sound in water travels faster than in air and even faster in a solid such as wood and even faster in a solid like metal. But even at sound's fastest light will beat it out.

Answer 4

Light travels through a medium, known as electromagnetic fields that are present everywhere in the universe. The speed of light is an inherent property of electromagnetic fields, that can be derived from Maxwell's equations. Maxwell's equations govern electromagnetic fields and electricity and magnetism. They are considered the "Newton's Laws" of electricity and magnetism.

Sound's speed is limited by the distances of the atoms from each other in a gas, liquid, or solid. So a higher density means a higher value for the speed of sound.

Answer 5

Sound and light are totally different type of waves. In simple terms, sound (acoustics) in air is caused by the vibration of the air particles. Light waves are electromagnetic waves of a much wider spectrum of frequencies. The speed of waves are much different too. According to einstein, nohing can travel faster than the speed of light. The sound vibration travels much slower than light waves.

Answer 6

Sound is itself transmitted by the air vibrations, and hence it is slower due to the inertia of the gas molecules involved. Light by contrast ignores the air, and just travels through on the electromagnetic wave system.

Answer 7

Light is electromagnetic and can travel through space. Sound is shear or compression waves which can only travel through matter, and matter will also slow the waves down.

Answer 8

Hi. Sound counts on molecules touching each other to transfer energy. This slows the sound down.

Answer 9

Ressistance- What is the speed of dark to light speed?

The same!

Answer 10

there's more energy in light
