Michelson had light source on a mountain that he pulsed using a rotating mirror. Far away, on another mountain a fixed mirror returned his pulses to him. By comparing the transit time he came up with a close number. As equipment( esp. the timing mechanism) improved so did the number.

Who contributed to the evidence of electromagnetic waves and their link to light?
James Clerk Maxwell derived the existence of electromagnetic waves. Due to its speed (as calculated from his equations), which is the speed of light, he concluded that light is probably also an electromagnetic wave. This was confirmed later.
Is it light speed or the speed of light?
speed of light I think well it sounds right:)
Is it possible to travel at the speed of light in water?
The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
Is the speed of light or sound faster?
The speed of light is about 880 thousand timesfaster than the speed of sound.
Is the speed of sound as speed of light?
The speed of light is much greater than the speed of sound.
Why is the speed of light 186000 miles per second?
Consult Maxwell's Equations. It is derived from electrical and magnetic constants.
Is speed a derived quantity?
Velocity is a derived quantity. Speed is velocity without direction. Velocity is derived from distance and time.

Can the speed of light be ligislated?
Sort of. The meter is currently defined to be exactly the distance that light, in a vacuum, travels in 1 / 299,792,458 of a second. The result of this is that the speed of light is DEFINED to be a certain value (299,792,458 meters / second); the meter is derived from the speed of light. Of course, you can't legislate to make the speed of light in a vacuum faster or slower; or rather, if you do, light won't care about such legislation. The legislation only affects the numeric values assigned to such a speed.
How are time and distance related?
Time is a derived parameter from distance; d=ct gives t=d/c where c is the speed of light.
Is it the speed of light or light speed?
Is what the speed of light or light speed.ANSWER300,000 km/s
Why do you age more when you approach the speed of light?
Actually you would age slower. Time passes more slowly at higher speeds. For a detailed explanation (how this result is derived), read an article about the Special Theory of Relativity - however, it is based on the basic assumption that the speed of light is constant. This strange fact - that the speed of light (in a vacuum) is constant - has been confirmed by countless experiments.
Is the speed of light is a basic unit or a derived unit?
The speed of light, abbreviated as "c", is a fundamental constant. It is 299,792,458 meters per second, and the length of the meter is DEFINED AS being 1/299,792,458th of the distance that light travels in one second. So it is a "basic unit". We generally use 300,000 km/second or 186,000 miles per second as "close enough" approximations of the speed of light.

Is it possible to travel at the speed of light in water?
The speed of light in water is less than the speed of light in space. Only light can travel at the speed of light.
Which was the fastest the speed of light or the speed of sound?
speed of light
What is faster Speed of Light or Speed of Eyesight?
The speed of light.
