WebIn fact, the speed of light in a vacuum c is so important that it is accepted as one of the basic physical quantities and has the value. c = 2.99792458 × 108m/s ≈ 3.00 × 108m/s. … WebQuestion: what's the speed of light. Wrong answer: 300,000,000 meters/second. Correct answer: it depends on the medium! Note to Microwaves101 readers: most textbooks use the term "phase velocity" denoted by vp interchangeably to also mean "velocity of light in a medium". This gets confusing, so we will avoid doing it and denote "velocity of ...
