lenses

Provides information about lenses, looking at how they work in the eye, and in eyeglasses, and presents a series of experiments and investigations that can be done with a hand-held magnifying lens.

In the discovery room at the science museum, Taina and Mark learn about prisms and lenses.

By doing the simple science projects, young scientists will discover how distance affects images made by a convex lens, observe a wave model of polarized light, and explore the science behind mirages.

Provides information about photo science; including tips, history, lenses, medical photography and photos taken in space. Gardner also presents the scientific method and gives ideas for science experiments.

"This book looks at what reflections are and how we can use them. Mirrors reflect light back at exactly the same angle. You can make a 'mirror book' to explore symmetry and multiple reflections. Why does a straight straw look bent in a glass of water? Experiment using air, oil, and water to see how different materials affect the speed of light. Look at how our eyes use reflected light to see and make a pinhole camera to show how the eye works."--Provided by publisher.

"Though we take light for granted, the world's greatest scientists have long puzzled over its nature, properties, and behavior. Its incredible speed, mysterious frequency, relationship to color, form of travel, and uncanny ability to reflect, refract, diffract, and be absorbed altogether make light the ever-elusive quarry of science's greatest hunters of knowledge and understanding. This is the enthralling account of their investigations and discoveries, their conclusive insights and ongoing questions, enhanced by full-color photographs and explanatory visual aids. If you thought you knew everything there is to know about light, think again and read on" -- Provided by publisher.

"Over the last five centuries, optical engineers have created world-changing instruments and technologies, such as telescopes, microscopes, cameras, and televisions. Learn how the study of light and vision can be combined with the engineering design process to turn a bright idea into a reality."--P. [4] of cover.

Describes how scientist Eric Baery is studying octopus eyes in an attempt to create better cameras and lenses.
