Light waves travel at approx 300,000 kilometres per second, sound at approx 0.343 kilometres/second.
Light waves can travel in vacuum or through some media (there is no such word as mediums!). Sound waves cannot travel through vacuum: they needs a physical medium.
The speed of sound varies in different mediums, different temperatures, and different pressures.The speed of sound varies depending with the temperature, altitude and air.
speed of light is different in different mediums because each medium has it's own refractive index,due to which speed of light changes in every medium. As light consists of different colors and each color has it's own speed in different mediums.
The denser the medium, the faster sound travels in it.
The speed of light through different media is equal toSpeed of light in vacuum/Refractive index of the medium .
No. Sound travels slowly like a turtle, while light zips along like a rabbit.
different mediums have different density so speed of sound will change.hence, the direction of sound wave will change.
The speed of sound of change for mediums of different densities compressibilities and temperature because different densities give different resistance to the sound. It blacks more of ht sound the denser the object is,, and give more when the object is less dense.
speed of light in different mediums is inversely proportional to the density of the mediums. in a medium with a higher density,the light rays are difficult to penetrate into the medium and hence the spped decreases. as the density decreases , speed of light increases.
Basically the denser the medium, the slower the light.
Its speed and wavelength change.
It is simply called a change in speed.
Short Answer:The speed of a wave depends very much on the type of the wave and the medium though which it moves.More:Sound waves in air, water waves in the ocean and light waves in space are waves different waves in different mediums and with vastly different speeds. Each of these types of waves changes speed dramatically in different media. Ripples move at a different speed than ocean waves. Light in glass travels at about two thirds of the speed of light in a vacuum and sound waves in metal are much faster than sound waves in air. Another good example is waves from an earthquake, which occur in two different forms and which are regularly experienced as separate shocks from an earthquake.
The speed of light, c is greatest in a "vacuum" and is slowed when passing through transparent mediums such as water, glass and crystals. Different mediums reduce the rate of c differently, depending on a number of factors.
This is called refraction due to differences in the speed of light in the different mediums.
Sound waves cause vibrations in the medium's atoms travel through it. When the mediums atoms are held closer together (higher density), they can pass the energy from the sound wave to nearby atoms much more easily and much more quickly!
Assuming you mean the speed of sound in air, the speed of light (in a vacuum) is about 800,000 times larger. However, sound has very different speeds, depending on the medium in which it travels.Assuming you mean the speed of sound in air, the speed of light (in a vacuum) is about 800,000 times larger.

when we talk about different mediums..speed of sound is directly proportional to the density..(fastest in solids and slowest in gas)...but when we talk about the same medium..speed of osund is inversely proportional to density
For most mediums, a higher temperature results in higher density, and sound travels through denser mediums faster than through less dense mediums, so a lower temperature generally increases the speed of sound waves.
Further in a given period of time? No. The speed of light is constant in all mediums. The speed of sound, however, which is a physical wave, does change.
The speed of light is much greater than the speed of sound.
Speed of sound is maximum in STeel or solid.. if we compare the speed of sound in different mediums like vaccuum,water,solid..we will find it decreases with maximum in soild then liquid and then vaccuum
The speed of light in vacuum is roughly 874,000 timesthe speed of sound at sea level.Putting it the other way...The speed of sound at sea level is about 0.0000011 times the speed of light in vacuum.
The difference in speed in different mediums cause light to bend from one medium to another if the angle is not 90 degrees.
The speed of light is about 900,000 times as fast as the speed of sound in air.
