摘要：AbstractToday and in an educational dimension, the history of light plays a key role in teaching modern sciences of matter. Whether it is a discipline involving molecules, atoms, particles, elementary particles . (usually matter and energy), the learner is primarily interested in the mechanism of a theory and mathematical proofs rather than the origin of the theory in question or why it was discovered, where and when. Returning to these historical facts could solve some learning problems of phenomena intimately tied to the concept of light. These problems are most likely related to the deliberate negligence of their history in the educational process. Indeed, teaching the history of science would only make science friendly. The work we have done describes the evolution of the concept of light and its interaction with matter as a factor of technological innovation from antiquity to the middle of the 20th century. This period is a testimony to the true development of spectroscopy we know today.
