Calculate the speed of light.

[ta3]

---

If an object traveling 75% of the speed of light and head on to a light travel towards to the object (and we all know that speed of light is constant(300 km/s)). What is the calculation that make the speed of light(300 km/s) constant? I mean how to derive in mathematical solution that we could say that indeed the speed of light is constant.

I see... sorry, I don't quite follow.

(and we all know that speed of light is constant(300 km/s)).

I think of speed of light as the universal speed limit if it is not used in a mathematical equation. If it is used in a mathematical equation, it would be "c"(speed of light in a vacuum which is constant). But Im no physicist so I don't know if that is accurate. hahaha

nosebleed! whew!

you can not calculate it, its already constant... nuff said.

This is my gathered data E=mc²
Maybe the question there is how you get the value for speed of light.

study maxwell's equations (on electromagnetism). you will find your answer.

kalimot na ko pero pwd man makuha ang c gamit ug wavelengths.

Your first error is assuming that the speed of light is constant in a vacuum--it's not.

Straighten that out, then rephrase your question.

Really? How did Einstein got that number of speed of light which is 671M miles per hour? Out of thin air? surely he's not guessing it either...nuff said.
