Física 7.01 Hipótesis de Planck muy fácil. Catástrofe ultravioleta, cuerpo negro, consecuencias.

In this video, we systematically explain the fundamentals of Planck's Law. First, we explain the historical context: the response to the ultraviolet catastrophe in predicting blackbody radiation using classical electromagnetism. We explain how Max Planck, in 1900, resolved this discrepancy between theory and experimentation with his famous formula, which includes Planck's constant. Finally, we discuss the consequences of this crucial discovery and solve a problem that demonstrates the varying dangers of different types of radiation in the electromagnetic spectrum. -Easy question: Calculate the wavelength of radiation with an associated energy of 5 picojoules. To which part of the electromagnetic spectrum does it belong? -Difficult question: We illuminate a blackbody with a 500 nm wavelength laser pointer for 1 minute and observe that its energy increases by 20 millijoules. How many photons per second does the laser pointer emit?
