Is the speed of light a physical constant?
It’s good to know the speed of light, one of the physical constants, since it is used in many calculations. Nick Koudis/Getty Images Todd Helmenstine is a science writer and illustrator who has taught physics and math at the college level. He holds bachelor’s degrees in both physics and mathematics. Need a value for a fundamental physical constant?

What are the physical constants of the SI base units?
Since May 2019, all of the SI base units have been defined in terms of physical constants. As a result, five constants: the speed of light in vacuum, c; the Planck constant, h; the elementary charge, e; the Avogadro constant, NA; and the Boltzmann constant, kB, have known exact numerical values when expressed in SI units.

What do the symbols in a physical quantity mean?
Sometimes, the symbol may be the first letter of the physical quantities they represent, like, which stands for distance. Other times, they may be completely unrelated to the name of the physical quantities, like c, which stands for the speed of light. They may also be in the form of Greek characters, like λ, which stands for wavelength.

What is the difference between a constant and a variable?
The constants like variables but their values don’t change during the program executes. The bad news is that Python doesn’t support constants. To work around this, you use all capital letters to name a variable to indicate that the variable should be treated as a constant. For example:
