What is what mach is the speed of light?

The speed of light, represented by the symbol c, is a constant value in physics and is approximately equal to 299,792,458 meters per second (m/s). This speed is the maximum speed at which information or energy can travel in the universe according to the theory of relativity proposed by Albert Einstein.

The speed of light is considered a fundamental constant of nature and plays a crucial role in many aspects of physics, including the theory of special relativity, the study of electromagnetism, and the understanding of the nature of space and time.

In terms of the Mach scale, which is a measurement of an object's speed relative to the speed of sound in a medium, the speed of light is far greater than any speed that can be achieved by an object traveling through a medium such as air or water. As a result, the speed of light is said to be infinitely faster than the speed of sound, and therefore cannot be expressed in terms of Mach numbers.
