Light travels slower through a medium. Generaly the dencer the medium the slower light travels.
Light travels fastest through a vacuum assuming its speed is not being affected by gravity which also affects the speed of light.
Examples. A very very thick piece of glass will appear thinner than it actually is and a streight stick will appear to bend if put into water at an angle.

∙ 14y agoWell we know that light is the most fastest travelling thing(300000 km/s). However the change of the speed of light in any medium is very slight and cannot be noticed. It is concluded that light travells the fastest in vacuum

∙ 9y agoLight travels in free space with a speed 300 thousand kilometer in one second. This is the highest speed in the physical world. But as light travels in water or glass then its speed is found to be reduced. In case of glass its speed comes to be 200 thousand kilometer in one second. In case of water, its speed is found to be 225 thousand kilometer in one second.

In what medium the speed of light will be minimum?
The speed of light is a set speed at which all electromagnetic waves travel at in a vacuum. It is 3*10^8 meters/second... That being said, when light, or any other EM wave, travels through a medium it will slow down. Every material has an index of refraction which is the ratio of the speed at which light travels in a vacuum, to the the speed it travels in that material. If you know the index of refraction, you can use Snell's law to determine the speed light will travel through a specific medium. Every medium is different, however a rule of thumb is the denser the medium, the slower light will travel through it. For example, light travels faster in the atmoshpere than it does in water.
Why does light travel faster in empty spaces?
Light travels faster (up to the speed of light) in a vacuum, which is empty space. Light travels slower through a medium (matter).
Through what do seismic waves travel fastest?
seismic wave travels faster through solid rock and slower through water, but i dont know why!
Do the planets closest to the sun travel slower or faster around the sun?
faster
Can a comet go a light year in 1 second?
No. A light year is the distance light travels in a year, and nothing can travel faster than light. Therefore, the quickest that anything could travel a light year is 1 year. A comet travels much slower than light.
Why does sound travel faster closer to the ground than in the air?
The stiffer meduim- travels quicker The denser the medium-travels slower
Can sound travel through ground?
hi, sound does travel through ground. the speed at which sounds travels depends on the medium. the denser the medium, the slower it travels and stiffer the medium, the faster it travels.
Does sound travel 4 times faster in liquid?
No it actually travels slower.
In what medium do waves travel faster?
Waves travel faster in denser mediums. For example, sound travels faster in water than air.
Does sound travel faster in heat or water?
Sound doesn't travel in heat. It travels in a physical medium.
Which medium does sound travel fastest in?
Sound travels faster in solids than it does in liquids. thus, sound travels faster in liquids than it does in solids
Could sound travel faster in solids or gasses?
Sound DOES travel faster in solids than in gases. The higher the density of the medium, the faster the sound travels.
How sounds travel in different mediums?
Sound travels faster the more dense the medium
Does light travel faster in diamond or water?
Light travels slower through denser media, so it travels faster through water than through a diamond.
What is the fact of medium on the speed of sound?
Sound travels at different speeds depending on the medium. Sound will travel the fastest through solids.
What happens to the speed of sound waves when it travels through different mediums?
In general, sound will travel faster through a medium that's more dense, and slower through one that's less dense.
Does sound travel faster or slower through a solid than through air?
sound travels faster through a solid than through air
