The transition between wavelengths and energy is a core concept in several fields of physics, including Quantum Physics, Spectroscopy, and Optics. This conversion is vital to understanding the behavior of electromagnetic waves and quantum particles. In this tutorial, we will explore the formula that allows us to convert a given wavelength into its corresponding energy.

The energy of a photon can be calculated using the following formula:
The above formula is a direct application of the Planck-Einstein relation, which connects the energy of a photon to its frequency. Max Planck first introduced this relation in 1900, and Albert Einstein later extended it to include the photoelectric effect in 1905.
This formula is widely used in spectroscopy, where it helps scientists to understand the energy levels within an atom or molecule. It's also used in solar panel technology to calculate the maximum possible energy that can be harnessed from sunlight.
Max Planck and Albert Einstein are the key figures related to this concept. Planck's work on black body radiation led him to propose the idea of quantized energy levels, which Einstein later expanded on with his theory of the photoelectric effect. Both scientists received Nobel Prizes for their contributions to Physics, Planck in 1918 and Einstein in 1921.
Understanding the relationship between a photon's wavelength and its energy is a critical aspect of quantum physics, spectroscopy, and various other branches of physics. It enables us to understand light's behavior better and facilitates numerous technological advancements. This connection between the seemingly disparate concepts of energy and wavelength embodies the fascinating nature of the physics discipline.
