Light travels slower through denser media, so it travels faster through water than through a diamond.
it travels faster through air.
Air
It travels faster thru air
water
The speed of light in any medium is given by its speed of light in vacuum divided by the refractive index of the medium and so light will travel faster in water than in glass since refractive index of glass is greater than that of water.
yes they travel faster :)
Water is denser than air . Hence light travels faster in air than water.
Slower in water.
Light travels much faster than sound, through wood.
Since air has a lower optical density than water, light waves can travel faster in air.
it travels faster through air.
they travel faster. Light waves travel more QUICKLY as they enter water. ^^ whoever done this;; thanks! i really needed the answer....
Air
yes
Air.
metal since it is solid
The speed of light in water is approx 225,400,000 metres per second. Its speed in kerosene is 215,700,000 metres per seconds. So it travels around 4.5% faster in water.
