Question

Calculate the speed of light in glass whose refractive index is 1.39

Answer 1

Answer:

: c = f where: c = the speed of light = 300, km/s or 3.0 108 m= the of light, usually measured in meters o (1 Å = 10-1m) f = the fqu at lighwaves pss, measured in units of per seconds (1/s).

the speed of light =

299 792 458 m / s
