Calculadora de errores

About this app

This application is used to calculate the errors in experimental measurements of various laboratory experiments related to the phenomena of interference and diffraction of light. In particular it is laboratory practices carried out in the course of Physical Optics II of the School of Optometry at the Complutense University of Madrid. The application displays a brief summary of each practice (button "View Summary"), including the purpose and methodology. Calculator errors in each practice measured directly with instruments measuring values ​​are entered; ruler, tape measure or goniometer, and errors are also introduced, ie the details of these instruments. Respecting the values ​​must be entered units are indicated in each box. The application calculates ( "Calculate" button) values ​​of the errors of the magnitudes that are subsequently calculated with these direct measures. That is, the calculator throws errors indirect measures. Indirect errors are unrounded.
The program includes the following laboratory experiments. The first deals with light interference using a Fresnel biprism. Analyzing the distribution of light that appears (pattern interferential fringes) the wavelength of the laser used is determined. The second experience with the phenomenon of diffraction using simple objects; slit, circular aperture, diffraction grating. Observing and measuring on the diffraction pattern generated object size information is obtained. The last experience analyzes determining the wavelengths of a light source as an element disperser using a diffraction grating.

En el apartado de medida de longitudes de onda, los ángulos medidos con el goniómetro se expresan directamente en grados (antes se introducían grados y minutos).
