luminal speed
  • SI süsteemi defineeritud konstant
  • defining constant of the SI
  • scalar quantity equal to the speed of electromagnetic waves in vacuum
valguse kiirus vaakumis
Usage examples
  • Erirelatiivsusteooria kohaselt on valguse kiirus vaakumis kiiruse ülemine piir, millega tavapärane aine või energia (ja seega iga signaali kandev teave) võib kosmoses liikuda.
Good to know
  • Valguse kiiruse vaakumis c leppeliselt kinnistatud täpne väärtus SI-s on 299 792 458 m/s.
speed of light in vacuum preferred
Usage examples
  • According to the special theory of relativity, the speed of light in vacuum is the upper limit for the speed at which conventional matter or energy (and thus any signal carrying information) can travel through space.
Good to know
  • Defining constant "speed of light in vacuum" c in the SI is 299 792 458 m/s.
