2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/160485We introduce some new experiments where light diffraction is demonstrated with simple elements: white light diffraction with a coin, construction of a diffractive lens by holography, diffraction properties in digital discs and an interesting experiment that generates images with them. This experiments lead to the idea of a new optics that is entirely diffractive, which is a trend in development for its construction facilities, weight reduction and other benefits it causes.12 pages, 14 figuresPhysics EducationOpticsExperimentos simples demostrando algunas propiedades de lentes difractivas y redes espiralestext
