The speed of light simplified as c, is a distance light travels over a specific duration of time . The measured distance is 299,792,458 meters and the duration of time it takes light to travel the distance is one second . When we write down or type the speed of light, it is written or typed 299,792,458 m/s , which states light travels at 299,792,458 meters per second .
Too give you an idea of how fast this actually is , imagine travelling at 670616629 miles per hour or flying around the Earths circumference 26,945 times in one hour .
The speed of light is explained in being a constant speed whilst the light is travelling through a vacuum space . What this means is that 299,792,458 m/s remains the same value throughout the lights journey of the vacuum . A vacuum space is any space that is without a medium and it is explained that when light enters a medium space , that the medium slows down the lights journey . There is several types of mediums, gaseous , liquid , solids and possibly spatial fields .
Although a medium obstructs the impetus of light , once light exits the medium space , it then accelerates back to the speed of light 299,792,458 m/s .
