Strange as it may seem, the speed of all electromagnetic waves was predicted long
before it was ever measured. After the speed was predicted, measurements of light-
speed supported the growing suspicion that light is electromagnetic radiation, because
the measured speed was so close to the predicted speed.
Measuring the speed of light is not easy, and several clever methods had to be invented
in order to do it. Calculus was almost certainly used at many points in the application
of these methods.
The first determination of the speed of light was by Ole Roemer. As far as I understand it, that calculation doesn't involve calculus.
It is certainly used in calculus, just as calculus can be used in trigonometry.
None. The speed of light is usually assumed to be constant. The symbol used to represent the speed of light is "C", as in E=MC2. Then why is it called a variable speed?
yes it is
The definition of speed: speed = distance / time. You can also write this as distance = speed x time. This is used to do various calculations related to speed. The above is actually only valid for a constant speed. If the speed changes over time, speed - or more precisely velocity - is defined (using derivatives) as v = ds/dt. However, you need to have basic notions of calculus to work with this.
That is used as a conversion factor between mass and energy.
In mathematics, Newton shares the credit with Gottfried Leibniz for the development of the differential and integral calculus. He also demonstrated the generalised binomial theorem, developed the so-called "Newton's method" for approximating the zeroes of a function. He used the methods of calculus to solve the problem of planetary motion.
The difference between Leibniz calculus to Newton calculus was that Leibniz developed Newton's calculus into the calculus we all know today. For instance, diffentiation and intergration, limits, continuity, etc. This type of calculus was the pure mathematics. On the otherhand, the calculus which Newton found was that used in physics, such as speed and velocity which helped with physics greatly. Today, calculus not only used in just mathematics or physics, but used in finance, as well as exploited in engineering.

Constant is the speed of light and as the speed of light cannot change it is 'constant'
Mainly Leibniz's and Newton's version is used in Calculus Textbooks.
Pretty close ... that figure is about 99.85% the speed of light. (You used 186,000 miles per second. We used 186,282 .)
No.
A new discovery has indicated that a copper light could reduce the effects of rusting on things such as vehicles. This is an important discovery that could change standard practices on a global level.
No. They never traveled at the speed of light, and have always appeared tired.
In vacuum it is 299792458 metres/second. It is used for light to get from one location to another.
Speed of light in a material = c / (refractive index of the material) . ' c ' = speed of light in vacuum = 299,792,458 meters per second.
