The article proposes the use of virtual technological resources to carry out laboratory practices in the career of Higher Technician in Medical Biophysics. It is argued that virtual simulations can contribute to the development of experimental skills and the learning of physical knowledge. In addition, it is mentioned that these virtual practices can help students develop skills in the use of Learning and Knowledge Technologies (LKT). Instructions and guidelines are provided for the development of activities and the preparation of the corresponding report. The use of virtual simulators in the teaching of Physics is highlighted, specifically for the photoelectric effect. These simulations are an alternative when the necessary infrastructure is not available to carry out traditional laboratory practices. [Extracted from the article]

The following article describes how to calculate the Planck constant as the slope of the line of the graph of maximum kinetic energy as function of frequency via light-emitting diodes emitting at different frequencies in the visible region of the spectrum. [ABSTRACT FROM AUTHOR]

Einstein's hypothesis is posed and applied to the development of the Theory of Photoelectric Phenomena, the Bohr's Theory of the Hydrogen Atom and the main laws of Photochemistry. An example of interaction process not satisfying Einstein's hypothesis known as multiphoton absorption is analyzed and one of its applications is described. [ABSTRACT FROM AUTHOR]

In this work a source radioactive of radiation gamma is simulated with energy in the range from 0.030 to 3 MeV and a cylindrical detector of NaI(Tl) of 2x2 is simulated, this is similar to the system that possesses the group of Radiological Physics of the U.N. - Sede Medellín and that it is used for in vivo measures of thyroid. The different interaction types were simulated in the overlap of Aluminum of 0.5 mm and the NaI(Tl) crystal, having in consideration the coefficients for photoelectric effect , compton effect and production of pairs in the different medium. It was obtained in the spectra the continuous region due to the compton and their court, the escape picks in the case of production of pairs and the corresponding photopeak, like it is reported theoretically in the literature and reproduced the spectrum with the form gausiana, considering this distribution type for each energy emitted gamma.

The article shows that the text by Einstein in 1905, where he formulates his theory of the "quantum of energy" for the electromagnetic radiation, didn't have as fundamental object to explain the photoelectric effect, and that his theory of the "quantum of energy" didn't have as base the Planck's formulation for the radiation of die black body, as it is generally believed.
