How many machs is the speed of light?

Question:- How many machs is the speed of light?

Answer

The speed of light is awe inspiring 299,792,458 meters per second in space. This speed is so massive that the most tractable and easier way to express it is by means of the Mach number which is the ratio of the speed of an object to the speed of sound in the same medium.

When it comes to the medium through which the speed of light travels this is air at Standard Temperature and Pressure, for which the speed of sound is about 343 metre per second Further, and completely differently, the speed of light can be compared to the speed of sound by measuring both in the same medium: it is 343 m/s for sound in air at standard temperature and pressure. As a result, the speed of light is about 873,030 Machs, a very high figure, pointing to the incredible velocity of light in space.
