Physical constants are the quantities that remain constant in physical laws and equations. These constants play a significant role in physics and engineering, as they help us understand the fundamental principles of the universe.

4 Most Common Types of Physical Constants

Physical constants are the quantities that remain constant in physical laws and equations. These constants play a significant role in physics and engineering, as they help us understand the fundamental principles of the universe. In this article, we will discuss the four most common types of physical constants.

Fundamental Physical Constants

Fundamental physical constants are the most basic and fundamental constants in physics. These constants do not depend on any other physical quantities and are considered to be universal. The speed of light, Planck’s constant, and the gravitational constant are some examples of fundamental physical constants. The speed of light is a constant value that represents the speed at which electromagnetic waves propagate in a vacuum. Planck’s constant is a constant value used in quantum mechanics to relate the energy of a photon to its frequency. The gravitational constant is a constant value used to relate the force of gravity between two objects.

Electromagnetic Constants

Electromagnetic constants are the physical constants used in the study of electromagnetism. These constants include the permittivity of free space, permeability of free space, and the characteristic impedance of free space. The permittivity of free space is a measure of the resistance encountered when forming an electric field in a vacuum. The permeability of free space is a measure of the resistance encountered when forming a
