Example Formula

The energy associated with a wave or particle can be determined using the formula:

E = h × f


  1. E: represents the energy of the wave or particle.
  2. h: refers to Planck's constant (h = 6.62607015 × 10-34 J·s).
  3. f: denotes the frequency of the wave or particle.

Who wrote/refined the formula

The relationship between frequency and energy is derived from quantum mechanics and was established by Max Planck in 1900. Planck's constant, represented by the symbol "h," is a fundamental constant in Physics that relates the energy of a quantum particle to its frequency. Planck's work on quantization revolutionized our understanding of energy and laid the foundation for the development of quantum theory.

Real Life Application

The conversion of frequency to energy has various applications in different branches of Physics. In the field of spectroscopy, for instance, the energy of electromagnetic waves or photons is determined by their frequency. This enables scientists to analyze the composition and properties of materials based on the energy levels at which they interact with light. Frequency to energy conversion is also relevant in particle physics, where the energy of subatomic particles, such as electrons and photons, is crucial in studying their behavior and interactions.

Key individuals in the discipline

Max Planck's contributions to Physics, particularly in the development of quantum theory and the concept of energy quantization, earned him the Nobel Prize in Physics in 1918. His groundbreaking work laid the foundation for future advancements in understanding the fundamental nature of energy and matter.
