According to the Princeton experiment, a speed of 57,747,544 miles per second was achieved.
Speed. All photons traveling through a vacuum travel at the speed of light.
The speed of light depends on the refractive index (optical density) of the medium through which it travels. It is not affected by temperature.
The speed of light in vacuum is exactly 299.792,458 m / s The speed of light in air is roughly 299,702,458 m / s
That would depend on the medium which the light is traveling through.
No, the speed of light is not the same in all optical media. It changes depending on the medium through which light is traveling, such as air, water, or glass. The speed of light is slower in denser media compared to a vacuum, where it travels at its maximum speed.
When the light is traveling through vacuum.
Speed. All photons traveling through a vacuum travel at the speed of light.
Electrons are able to travel close to speed of light.
ANY light traveling through the same medium (stuff) has the same speed.
The speed of light is determined by the electric and magnetic properties of the stuff it's traveling through. The "light" itself is just electrostatic and magnetic fields traveling together through the stuff. Change the electrical properties of the medium, and you change the speed of light through it.
is a constant, about 300,000,000 m/s.
The speed of light is the result of the electrostatic and magnetic properties of the medium through which it's traveling. The speed changes only when those properties change.
No, light does not travel at the same speed through all transparent media. The speed of light can vary depending on the medium it is traveling through. It typically travels slower through materials like glass or water compared to its speed in a vacuum.
The speed of light depends on the refractive index (optical density) of the medium through which it travels. It is not affected by temperature.

The speed of light depends mainly on what light is traveling through. The speed of light in a vacuum is 300,000 kilometers per second. The speed of light in other substances can be a little slower, and sometimes a lot slower.
The speed of light is 299,792,458 meters (186,282 miles) per second, when it's traveling through vacuum (nothing). When it's traveling through material media (something), the speed is always less than that, and depends on what the specific substance is. How to measure this speed is another whole subject.
