OPTICS UNDERGRADUATE EXPERIMENTS USING SMART (AND NOT SO SMART) PHONES.
Smartphones may be seen as miniature toolboxes to perform Physics experiments. In this paper, we present three different experimental optics designs mainly based on the light meter of a smartphone.

In this paper, we present three different experimental optics designs mainly based on the light meter of a smartphone. One is aimed at the precise study of Malus law and other effects associated to linearly polarized light, the second allows quantifying the energy distribution of diffraction or interference patterns projected on a screen, and the third demonstrates the so-called inverse square law obeyed by the illumination from a point-like source. These experiments allow to quantitatively demonstrate three fundamental laws of optics using quite inexpensive equipment. Los teléfonos inteligentes pueden verse como pequeñas "cajas de herramientas" para realizar experimentos de Física. En este artículo, presentamos tres "bancos ópticos" diferentes, basados fundamentalmente en el sensor de luz de los teléfonos inteligentes. Uno de ellos apunta hacia el estudio preciso de la ley de Malus y otros efectos asociados con la luz linealmente polarizada. El segundo permite cuantificar la distribución de energía en patrones de interferencia o difracción proyectados en una pantalla. El tercero demuestra la llamada ley del inverso del cuadrado, que obedece la iluminación asociada a una fuente puntiforme. Estos experimentos permiten demostrar cuantitativamente tres leyes fundamentales de la óptica usando equipamiento económico. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y custom: Copyright of Revista Cubana de Física is the property of Universidad de La Habana and its content may not be copied or emailed to multiple sites without the copyright holder's express written permission.
