c is a constant variable commonly known as "the speed of light", but more correctly the velocity of the speed of light ought to be called "the velocity of the speed of electromagnetic wave interactions".
And it is precisely 299,792,458 meters per second.
Yes, they travel some fast!
Copper is opaque to light - light can not travel though it.
the speed of light
it can travel from 380nm [nanometres] to 740nm
Darkness is the absence of light and will therefore travel at the speed of light (6x108m/s)
yes
at the speed of light
Speed of light.
Yes ... in a vacuum.
Approx 9.46 trillion km.
no from what i have learned light travels faster then sound
Nothing can travel faster than light in a vacuum.
