In a vacuum it travels 299792458 km per second?
The speed of light is around 300,000 km per second or 299,792,458 meters per second in a vacuum.
Would light travel the fastest through water glass or air?
It is not. The speed of light in any material is inversely proportional to the refractive index of that material. The refractive index of glass depends on the glass and so the speed of light varies between 156 and 204 million metres per second. By contrast, the speed of light in vacuum is nearly 300 million metres per second.Even in pure water ice, light travels at nearly 229 million metres per second. So there is no evidence whatsoever to support the question's claim of "fastest through glass".
does sound travels in all mediums, true or false?
False
Does sound travel better though air or water?
Sound travels better and faster in air because air has a lower density than water and the sound vibrations can travel faster through them and with more accuracy, whereas in water the vibrations slowly die out and do not travel well because the density of the water will likely muffle and obstruct the sound waves. sound travels better in air than in water as sound travels in vibrations.. it travels faster in water than in air but it travels better in air.....
Only sound energy travels in wavesTrue or false?
false because it can also travel out of waves
Is it true that Light travels faster in a material with a higher index of refraction?
true
Is this true or false light travels faster through water than it does through glass?
True
The speed of light is faster in a liquid true or false?
It travels faster in a liquid than in a gas, but it would travel faster still in a solid.

The sun's energy travels by electromagnetic bands.?
false

false
Is it true or false that the faster your heartbeats the slower your pulse will be?
That is false. Your pulse is a measure of your heart rate. The faster your heart beats, the higher (faster) your pulse will be.
