Let's study light. If you notice your sixth grader struggling in school, the you must prepare follow up tools. An example is this science book that talk about the electromagnetic spectrum, as well as the properties of light. Encourage your child to continue self-paced learning.

A lucid and illuminating examination of current theories, this volume offers a well-rounded perspective on the countless ambiguities of visual display, with particular emphasis on geometrical optical illusions such as framing and contrast effects, distortion of angles and direction, and the apparent "movement" of images. 240 illustrations. 1972 edition.

Thorough coverage of theory and applications of optics examines optical glass, light, elements of mirrors, prisms and lenses, construction of instruments, maintenance and more. Discussions include ship telescopes and spyglasses, boresight telescopes, fixed prism gunsight telescopes, magnetic compasses, and many other subjects. Extensive appendixes include a glossary, symbols, and formulas.

This undergraduate textbook presents thorough coverage of the standard topics of classical optics and optical instrument design; it also offers significant details regarding the concepts of modern optics. Its survey of the mathematical tools of optics grants students insights into the physical principles of quantum mechanics. Two principal concepts occur throughout: a treatment of scattering from real scatterers (leading to Huygens' principles, diffraction...

Extrait: "La substance que l'on doit employer de préférence est le résidu qu'on obtient par l'évaporation de l'huile essentielle de lavande, appliqué en couche très mince, par le moyen de sa dissolution dans l'alcool. Bien que toutes les substances résineuses ou bitumineuses, sans en excepter une seule; soient douées de la même propriété, c'est-à-dire celle d'être sensibles à la lumière, on doit donner la préférence à celles qui...

Este libro es el resultado de varios años de trabajo como docente y de la práctica clínica en el área de lentes de contacto. Aquí se describen la anatomía y la fisiología del segmento anterior del ojo, los diversos tipos de lentes de contacto, así como las filosofías de manejo en casos sencillos y en casos difíciles. La mayoria de las formas de adaptación son fruto del trabajo del autor y de la información obtenida con clínicos en lentes...

The obvious answer to the question of where heat comes from is the sun. But that's not all there is to it. In this book, you will learn about how heat can be produced through chemical reactions, electrical machines and friction. Are you keen to know more? Then grab a copy of this book and start learning.

The fully updated 2nd edition of this critically acclaimed book covers the exciting developments in light science of the past five years. Light Years is an engaging survey of everything we know of the universe's most enigmatic phenomenon and the remarkable people who have been captivated by it.
