Why does sound travel faster than light in water?

Why does sound travel faster than light in water?

Sound is produced by the vibration of matter, it travels by the matter interact with each other. So it depend on the medium, the density of water are larger than air, then the interaction between the water molecule are larger than air molecule. It leads to the speed of sound waves in water are larger than in air.

Why does light travel slower in water than in air?

And you might even know that light bends because it travels slower through glass or water than through air. Electromagnetic waves simply travel slower through glass than through air. So the wave crests are closer to each other, but the light still oscillates the same number of times per second.

Why does light travel faster in air than sound?

Light waves travel much faster than sound waves. Light waves do not need a medium in which to travel but sound waves do. Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water.

Does light or sound travel faster in water?

Speed of light in water is 3/4 of the speed of light in air. Sound travels three times faster in water than in air. Waves bend towards the slower region. Wave interacts with molecule and transfers it’s energy to the molecule.

What travels faster water or light?

The Cherenkov effect occurs when a particle carrying an electric charge travels through a transparent medium like water or air. In water, the speed of light is 200,000 km / sec. An electron must have an energy greater than 175 keV to go faster than light in water.

Why does sound travel faster in water but light travels slower?

Light travels faster than sound even in water. Light waves are electromagnetic transversal waves. They can travel through a vacuum and any particles they contact slow them down. So when they move through denser water they are slowed down more.

Why does light travel faster in water than glass?

In water, the refractive index is 1.3 and in glass, it is 1.5. Therefore, light travels faster through water, than it travels through glass.

What is faster than the speed of light or sound?

The speed of sound through air is about 340 meters per second. It’s faster through water and it’s even faster through steel. Light will travel through a vacuum at 300 million meters per second.

Why does light travel faster in air than glass?

Light travels faster in air than in glass because glass has a higher refractive index than air (in theoretical terms), and if we use common sense, we know that glass is a solid and more compactly packed than air, hence the photons of light will have more space and less resistance in air to travel than in glass or any …

Why light travels slower in glass than air?

As the refractive index of the medium increases, the speed of light in the medium decreases. The refractive index of glass is higher than air, so the speed of light will be slower in glass and faster in air.

Why is sound slower in air than in water?

If you are asking why sound is slower when it is in air than water, and why light is faster in air than in water, here is why: Light waves are electromagnetic transversal waves. They can travel through a vacuum and any particles they contact slow them down. So when they move through denser water they are slowed down more.

Do light waves travel faster than sound waves in water?

In a sense, the question is a little confused, because light waves travel faster than sound waves even in water. So, I guess what you want to ask is: the light waves travel slower in water than travel in air, but the sound waves travel faster in water than travel in air, what makes the different tendency?

Why does the speed of light travel slower in water?

Light travels slower in water.The speed of light is fastest in vaccum followed by air and then any other media which have refractive index greater than.This can be seen by the fact that light bends towards the normal while passing from air to water. Simplifying other answers…..

What factors affect the speed of sound travel?

For air and other gases, these will include temperature, humidity and altitude.The denser the medium, the faster sound will travel. Sound travels through air at the speed of 1,115 feet per second, through water at 4,757 feet per second and through iron at 16,404 feet per second.
