Answer:-
In physics, 'c' typically represents the speed of light in a vacuum. It's a fundamental constant with a value of approximately 299,792,458 meters per second (or about 186,282 miles per second). This speed is considered the maximum achievable velocity for any object in the universe, as dictated by Einstein's theory of special relativity. The speed of light 'c' is a crucial constant in various physics equations and has profound implications for our understanding of space, time, and the behavior of particles. It's a fundamental concept in the study of electromagnetism, optics, and the structure of the universe. So, 'c' in physics stands for the constant speed of light, a fundamental and unchanging quantity that plays a central role in our understanding of the physical world.
