Planck's constant is a fundamental constant in physics that describes the quantization of energy and the relationship between the frequency and wavelength of electromagnetic radiation. Some synonyms for Planck's constant include the Planck constant, the Planck quantum of action, the quantum of action, and the reduced Planck constant. It is often represented by the symbol "h" or "ħ" and plays a critical role in many physical theories, including quantum mechanics. The value of Planck's constant is fundamental to many calculations involving energy, frequency, and wavelength in the atomic and subatomic world. Overall, it is a crucial constant in physics that has helped shape our understanding of the universe.
