Planck's law
[/plɑːŋks lɔː/]
noun
Lei de Planck
1. A fundamental physical law describing the spectral density of electromagnetic radiation emitted by a black body at a given temperature, formulated by Max Planck in 1900
Planck's law explains why hot objects emit radiation across a range of wavelengths, with the peak shifting to shorter wavelengths as temperature increases.
A Lei de Planck explica por que objetos quentes emitem radiação em uma gama de comprimentos de onda, com o pico se deslocando para comprimentos de onda mais curtos conforme a temperatura aumenta.
2. The mathematical equation expressing the relationship between the energy of electromagnetic radiation and the frequency of the radiation, foundational to quantum mechanics
Planck's law introduced the concept of energy quanta, revolutionizing modern physics.
A Lei de Planck introduziu o conceito de quanta de energia, revolucionando a física moderna.
Planck's law is a cornerstone of modern physics taught universally in Brazilian and Portuguese physics programs. Max Planck's work is celebrated as pivotal to the development of quantum mechanics, one of the most significant scientific revolutions of the 20th century. The law is referenced extensively in physics, astronomy, and engineering disciplines across both Portuguese-speaking and English-speaking countries.
