No, the speed of light was not invented - it's a natural phenomenon.
Albert Einstein discovered the equation E=mc2. This tells us that if an object was to randomly turn into energy, the amount of energy would be equal to the objects mass multiplied by the speed of light twice.
What else can I help you with?
Electromagnetic waves travel the speed of light is it true?
It is true.
What is the the speed at which a wave travel through a medium?
the true answer is light speed
Who said that speed of light will be exact even if the person goes the half of speed of light?
Albert Einstein postulated that all observers, no matter what their velocity relative to the emitter of the light, will measure the light speed from that emitter as exactly the same as any other observer. The implicatons of this postulate have been proven to be true in every one of countless experiments in the decades since he made that postulate.
Why is the speed of light a fact?
A "fact" is basically anything you can state, especially if such a statement is true. Since you can say "light has a speed", and since that is true, it follows that it's a fact. Light through a "vacuum" is the meaning of "the speed of light." Light through glass is slower.
What of the following statements about the speed of light is true?
nothing can move faster than the speed of light in a vacuum APEXXX
When travels from air to glass its speed increases?
Of course not,it is not true. The speed of light decreases
Refraction occurs when the speed of light changes as it travels between mediums True or false?
True
Is true about the speed of light?
There are a number of possible statements that are true.The speed of light in vacuum is approximately 299,792,458 metres per second.The speed of light in vacuum is the same as the speed of other electromagnetic radiation in vacuum.No massive can be accelerated to travel at the speed of light.
What is the purpose of the speed sensor on a Mitsubishi Lancer?
to calculate the true speed of the car taking wind speed and direction into account, like a light aircraft (TAS - true air speed)
Is this true or false that light moves slower through water than through air?
Yes it is true. If c is the speed of light in air then in water it will be 3/4 of c Hence refractive index of water = speed of light in air/speed of light in water So refractive index = 4/3 = 1.333
Is it true that speed of light changes with medium?
Yes. The speed of light in a vacuum (or space) is 3x10^8 m/s. Light will travel slower in any other medium.
The speed of light is faster in a liquid true or false?
True, the speed of light is faster in a transparent medium like water or glass compared to its speed in a vacuum. This difference in speed is due to the different refractive indexes of the medium, which affects the speed at which light travels through it.
