The speed of light in a vacuum is 300.000 kilometers per second, that's 671.000.000 miles per hour.
No!! Speed of light: 299 792 458 m / sSpeed of sound: 340.29 m / s
The speed of sound is the velocity of sound through a mechanical (elastic) medium. And the difference is between the speed of sound and light is that Light travel faster then the sound.Light traveling through vacuum is roughly 879 thousand timesfaster than sound traveling through air at sea level.
This whole matter is a very slippery issue, because both light and sound havedifferent speeds depending on the material that each is traveling through. Also,there are many media through which one or the other of them does travel butthe other does not.Here are three situations:I ). VacuumLight travels. Sound does not.Speed of light = 299,792,458 m/sDifference = 299,792,458 m/s, light is faster.II ). One particular steel alloySound travels. Light does not.Speed of sound = 5,930 m/s.Difference = 5,930 m/s, sound is faster.III). Air at sea levelBoth travelSpeed of light = 298,925,574 m/sSpeed of sound = 340 m/sDifference = 298,925,234 m/s, light is faster.
It depends on the air temperature, but the conversion constant is the refractive index (RI). For air at standard temperature and pressure, the RI is 1.0002926. To convert the speed of light:va = c/RIva = 299,792,458/1.0002926va = 299704764.38594 m/sSpeed of light in vacuum, air, glassSpeed of Light in a Vacuum: 299,792,458 meters per secondSpeed of Light in Air: 298,925,574 meters per secondSpeed of Light in Glass: ~ 2x10^8 meters per second

what light?! head light, tail light, parking light, rear view mirror light, rear hatch light, underhood light, etc.
A traffic light is a light source as it emits light to signal drivers when to stop, slow down, or go.
Light (as in not heavy) = leicht Light (as in bright light) = Das Licht Light (as in light colored) = hell
Liwanag or ilaw= light ( light coming from a light source) magaan = Light ( not heavy)
A red light will be needed to combine with magenta light to produce green light. Green light is the complementary color to magenta, so by mixing red light with magenta light, the result will be green light.
light "not heavy" and light "not dark"
Mixing red light and blue light produces magenta light.
