This looks like a confusion with 186,000 MILES per second, which is the speed of light.

How fast is a light wave?
A light wave travels at almost 300,000 kilometers a second, (or 186 miles a second) in a vacuum. It slows down in water or other materials. It stops in a Bose Einstein condensate, but starts up again when the condensate turns to a different state of matter.
How long would it take to fall 167 feet?
Surely you're aware that a falling object accelerates under the influence of gravity. That acceleration manifests itself in the form of steadily-increasing speed, so the time required to fall 186 feet depends on how long it has already been falling. -- Immediately after it's dropped, the object falls the first 186 feet in 3.399 seconds. -- It falls the NEXT 186 feet in 1.408 seconds. -- It falls the next 186 feet in 1.08 seconds. -- It falls the next 186 feet in 0.911 second. -- It falls the next 186 feet in 0.802 second. . . etc.
What is velocity of light in vacuum?
The speed of light depends on the refractive index of the medium through which it is travelling. It reaches its maximum value in vacuum. This is approx 299,792,458 metres per second.
How fast does electromagnetic waves travel?
Electromagnetic waves travel through a vacuum at the speed of light. Whether that electromagnetic wave is a radio wave, a microwave, light, an X-ray or a gamma ray, it will move through a vacuum at a fixed speed -- the speed of light. We use c to indicate this speed, and it's about 186,282 miles per second, or exactly 299,792,458 meters per second. A link can be found below for more information.
How is reflected light waves and reflected sound waves are alike?
They are alike because they are using the same type of affect in regards to the laws of reflection , the only slight difference is the speed of light travels at a little bit faster then 186 thousand miles per second and the speed of sound travels at approximately 1116 ft per second which is equal to only about 768 miles per hour. So, they are alike because the use the same scientific law of reflection but sound travels much slower then light. You can only hear a sound from up to a certain distance away, but light seems to travel faster then the conscious brain can process. Only thru extreme brainwave entrainment therapy, the neurons are stimulated to produce more dendrites which are like fibric extensions of the neurons. These fibers increase the surface area available for receiving incoming information. The more dendrites the brain has at its disposal, the more quickly and smoothly it can process information. Then you would be able to see how the theory of relativity was not really a conjecture when you can scientifically prove it, with an EEG.
If you could drive through space at 75 mph how long would it take to reach the sun?
The sun is about 93,000,000 miles away, so at 75mph, this would take about 93 000 000 / 75 = 1 240 000 hours ~= 51 667 days ~= 141.5 years. Light travels at about 186 000 miles per second, so it takes about 93 000 000 / 186 000 = 500 seconds = 8 minutes 20 seconds to reach us. If the sun was to stop shining, we wouldn't know about it for a bit over 8 minutes!
Speed of light in one second around diameter 4880?
The speed of light is always 186 thousand miles per second.
How fast does light travel in milliseconds?
The "official" speed of light in a vacuum is 299,792,458 metres per second So in a millisecond - which is one-thousandth of a second - it will travel 299,792.458 metres. The Imperial equivalent of that is 186.2824 miles, or 186 miles, 495 yards, 5 inches.
How AC pass pass through a straight wire?
The actual direction of the electron flow (= current = electron stream) in an ac circuit is reversing 50 times per second. (or maybe 60/s in your country.)Remember, the speed of the current flow, the electrons will be a significant part of the speed of light.* So it can reverse flow in the whole circuit. Light travels 300 000 000 m/s. (~186 000 miles/s)Therefore in 1/50 of a second, it will travel 300 000 000/50 = 6 000 000 metres = 6000 km.* Actually, electricity in a wire will travel at .7 or so of the speed of tight.AnswerCurrent flow in 50-Hz system reverses direction 100 times per second, whereas the current in a 60-Hz system reverses direction 120 times per second.D.C. current flow is extremely slow, although its effect is practically instananeous. Depending on the size of the conductor, it is typically measured in millimetres per hour -an electron in a flashlight lamp is unlikely to travel through the filament during the lifetime of the battery.

How long would it take for light to travel per second?
Light travels for precisely one second each second.During that time, it travels a distance of about 300 million meters, or 186 thousand miles, if it's travelingin vacuum, a bit less if it has to plow its way through any material medium.
Speed of light per foot per second?
Velocity of light in free space = 299,792,458. meters per second (rounded). 1 meter = 3.28084 ft (rounded) 299,792,458 meters per second = (299,792,458 x 3.28084) =983,571,087.9 ft per sec (rounded)
What is the speed of light from sun to the earth?
The sun is roughly 8 minutes and 19 seconds away from earth in light speed!!! Imagine how far away it is in normal earth speed!?!? The speed of light is about 186,000 miles per second.
How is one hundred eighty-six thousand written in digits?
