optics

"This engaging book describes the properties of light waves, how they move, and the way our eyes receive them. Readers will learn that we see an object when light reflects from its surface and into the eye. A link to interactive activities online plus an activity in the book allow readers to create models that explore how to redirect and block the path a light wave travels."--.

Introduces readers to shadows and reflections. Its vibrant, hands-on examples help explain what shadows and reflection are, how they work, and how they can be used for communication.

Conduct your own experiments to discover more about the properties of light and how it works.

" Lightning[.] Rainbows[.] Auroras[.] Discover Earth's . . . natural phenomena in this adventure around the globe . . . Follow two intrepid explorers as they witness the Northern Lights, marvel in wonder at glow worm caves, go hunting for double rainbows, and dodge volcanic lightning"--Provided by publisher.

Helps children learn about light through simple science experiments and easy-to-follow explanations.

"One day, down by the pond, Simon meets another dog just like him. And that dog has a bone just like his, only better! How will Simon ever get him to trade, when the other pup knows all the same tricks . . .?"--Provided by publisher.

Optical illusions happen when we perceive something that?s not there or that appears to differ from reality. Scientists divide them into three different categories: optical, perceptual, and cognitive. Readers will be delighted to learn how all kinds of optical illusions work and how they can amaze their friends with the experiments in this entertaining volume. They?ll learn how to make a sequence of drawings seem to come to life, how to make a drawing appear 3D, how to draw the ?impossible? Penrose triangle, and much, much more. All activities and experiments are explained step by step through comprehensible and accessible text.

"The image is clear. Or is it? Optical illusions are tricks that our eyes and brain play on us to make us see things differently--like an image that shows two different things, depending on how you look at it. Explore ambiguous images and learn the science behind what makes them work. Then, take a turn making your own optical illusion. Get ready to be eye-mazed!"--Provided by publisher.

"This low-level book describes what light is and how objects can only be seen with light shining on them or from them. Simple explanations describe which materials light can shine through, what causes shadows, and what happens when you shine light on a mirror"--Provided by publisher.
