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 "see summary"), including the objective and methodology. Calculator errors in each practice directly measured with measuring instruments values ​​are entered; ruler, tape measure or goniometer, and errors are also introduced, ie the details of these instruments. The values ​​must be entered respecting the units are indicated in each box. The application calculates ( "Calculate" button) values ​​of the errors of the magnitudes that are subsequently measured with these direct measures. That is, the calculator throws errors indirect measures. Indirect shown without rounding errors.
The program includes the following laboratory experiments. The first deals with the interference of light using a Fresnel biprism. Analyzing the distribution of light that appears (pattern interferential fringes) the wavelength of the laser used is determined. The second experiment examines the phenomenon of diffraction using simple objects; slit, circular aperture, diffraction grating. By 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).
