Simple setup for wavelength estimation by using the Airy disk with didactical purposes
Author(s): U. Rivera-Ortega

Paper Abstract

In this manuscript a simple and easy to implement method that uses the Airy disk generated from a Fraunhofer diffraction pattern due to a circular aperture will be used to estimate the wavelength of the illuminating laser source. This estimation is based on the measurement of the Airy disk diameter, whose approximation is directly proportional to the wavelength of the light source and to the distance between the aperture and the image plane; and inversely proportional to the diameter of the aperture. Due to the characteristics and versatility of the present proposal, this is perfectly suitable to be applied in graduate or undergraduate physics laboratories or even in classrooms for educational and/or demonstrative purposes.
