Question

speed of light

Answer 1

The speed of light in a vacuum is approximately \(299,792,458\) meters per second, which is often rounded to \(3.00 \times 10^8\) m/s for simplicity. This speed is a fundamental constant in physics, denoted by the letter \(c\), and plays a crucial role in the theory of relativity and many other areas of science. Light travels slower in various media, such as water or glass, compared to its speed in a vacuum.
