About 2/3 its speed in a vacuum.
The speed of light is a constant, C= 300,000 km per second.

There are several different types of glass, and light has a somewhat different speed in each of them. On the average, the speed of light across all typical types of glass is in the neighborhood of 2/3 its speed in vacuum, or around 200,000 km/sec .
The speed of light is not limited in a vacuum - the speed of light is fastest in a vacuum. But that is what Einstein called the "Cosmic Speed Limit" - nothing can move faster than the speed of light in a vacuum, or even quite asfast.

The average speed of light in a vacuum is approximately 299,792 kilometers per second or about 186,282 miles per second. This speed is considered a constant in physics and plays a crucial role in understanding various phenomena in the universe.
The speed of light is constant for all types of electromagnetic radiation in a vacuum, regardless of frequency or wavelength. It travels at approximately 299,792 kilometers per second.
The speed of light is constant in a vacuum and does not change. It travels at approximately 299,792 kilometers per second in a vacuum.
About 2/3 its speed in a vacuum.
The speed of light is a constant, C= 300,000 km per second.
All colors of light travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second (186,282 miles per second). This speed is a constant in a vacuum for all wavelengths of light.
The speed of light in a vacuum never changes.
The speed of light is constant and is approximately 299,792 kilometers per second in a vacuum.
Light moves at a constant speed in all cases, which is approximately 299,792 kilometers per second in a vacuum. This speed is known as the speed of light and is a fundamental constant in physics.
Light does not accelerate in the traditional sense, as it always travels at a constant speed of approximately 299,792 kilometers per second in a vacuum. This speed is a fundamental constant in physics known as the speed of light.
The speed of light in a vacuum is constant at about 3 x 10^8 meters per second. The nature of the source of the light wave does not directly influence the speed of light in a vacuum. The speed of light is determined by physical constants in the vacuum, such as the permeability and permittivity of free space.
