Summary of Física Moderna 02 - Radiación térmica y el cuerpo negro

00:00:00 - 00:05:00

In this video, Max Planck, the founder of quantum mechanics, is discussed. His paper on the theory of energy distribution in the normal spectrum is considered the birth of quantum mechanics. In the video, the experimental facts and some results that were known about the experiment that later Max Planck explained are established. These facts include the power, frequency, and wavelength of radiation, as well as how it behaves as it increases in temperature. The relationship between the principles of quantum mechanics and radiation is also discussed.

• 00:00:00 In this video, Max Planck, the founder of quantum mechanics, is discussed. He read a paper on the theory of energy distribution in the normal spectrum on December 14, 1900, which is considered the birth of quantum mechanics. However, it wasn't until fourth century after his death that Niels Bohr and others developed the modern mechanics of quantum. That is the date that is considered the birth of quantum mechanics. In this video, we will establish the experimental facts and some results that were known about the experiment that later Max Planck explained. One of the experimental properties of radiation thermal is that condensed matter emits a continuous spectrum of radiation. If one graphs the intensity of radiation as the length of wave or frequency, one will see a continuous spectrum, without any emission lines. In a black body, radiation is emitted only in the thermal range. To create a black body, we make a cavity and let light enter it. When light hits the walls of the cavity, it rebounds and is consumed. The radiation then penetrates into these bodies and reflects off the internal walls, which can be, for example, a solid metal. We call this radiation the "radiance spectral" and define the radiant spectral radiance as the amount of radiation emitted in a specific frequency
• 00:05:00 In this video, we can see some of the characteristics of radiation, including its power, frequency, and wavelength. We also see how radiation behaves as it increases in temperature. Finally, we see how the principles of quantum mechanics are related to radiation.
