Lichtgeschwindigkeit
speed of light
light speed
symbol: c
Value in vacuum:
c = 299,792,458 metres per second = 1 Planck unit
(Sunlight takes about 8 minutes, 19 seconds to reach Earth, but, due to refraction, scattering, gravity and so on, about 100000 years to reach the surface of the sun from it's core)
- the maximum speed in the universe
- a constant of nature
- in a medium reduces the speed of light
- different types of light wave will travel at different speeds.
Approximate values:
300,000 kilometres per second
1,079 million kilometres per hour
186,000 miles per second
671 million miles per hour
173 astronomical units per day
