A stunning visual exploration of the power and behavior of light across the entire electromagnetic spectrum. Light allows humans to see things around us, but we can only see a sliver of all the light in the universe, also known as the electromagnetic spectrum. Renowned science communicators Kim Arcand and Megan Watzke bring the entire spectrum to life and present the subject of light as never before. Organized along the order of the electromagnetic spectrum--from Radio waves to Gamma rays--each chapter focuses on a different type of light. From ultraviolet light, used in microscopy to image plant cells and bacteria, to X-rays, which let us peer inside the human body and view areas around black holes in deep space, Arcand and Watzke show us all the important ways light impacts us. With hundreds of stunning full-color photographs, including new images from the James Webb Space Telescope, Light is a joy to read and browse.

Austin Richards takes readers on a visual tour of the electromagnetic spectrum beyond the range of human sight, using imaging technology as the means to 'see' invisible light. Dozens of colorful images and clear, concise descriptions make this an intriguing, accessible technical book. Richards explains the light spectrum, including visible light, and describes the advanced imaging technologies that enable humans to synthesize our own version of 'alien' vision at different wavelengths, with applications ranging from fire fighting and law enforcement to botany and medicine.

Any student or engineer working in optics or the field of laser technology will find this a fascinating read. The book begins by addressing the properties of light as seen in the everyday world: events such as refraction in a pool, lenses in the form of glasses, the colors of objects, and atmospheric events. Latter chapters explain these events at the atomic and subatomic level and address the use of electron and optical microscopy in observing the worlds unseen by the unaided eye. Exercises and activities will be found in an appendix, but the primary volume can stand alone if the reader so desires.

The 5 class sessions, of 45-60 minutes each, deepen student understanding of the electromagnetic spectrum, enabling students to detect and consider wavelengths other than visible light. Activities feature energy stations, including infrared (TV remote); microwave (pager); ultraviolet (black light) and other devices. Students come up with their own tests to see what blocks each wavelength, and what does not. They learn how these other wavelengths can be used to "see" things we cannot see with our eyes.

Since the dawn of time, electromagnetic energy has permeated through the universe, surrounding and interacting with everything it touches, illuminating, destroying and giving life. The colourful section of the electromagnetic spectrum we see in the form of visible light, rainbows and other phenomena is tiny when compared to its vast entirety. Using many parts of the electromagnetic spectrum have become common everyday occurrence for the majority of people on Earth, as it's been integrated into our lives in ways that we don't even think twice about it. This book illuminates many parts of the electromagnetic spectrum and its effects, the endless ways we have harnessed its energy, and how we interact and live with its influence. (less)

A visual exploration of the power and behavior of light, across the electromagnetic spectrum, and how it affects life on earth and everything in the Universe. Light allows us to see everything around us, but humans can only see a sliver of all light, known as the electromagnetic spectrum. Here, Kim Arcand and Megan Watzke present the subject of light as never before. Organized along the order of the electromagnetic spectrum, each chapter focuses on a different type of light. From radio waves, harnessed for telecommunications, to X-rays, which let us peer inside the human body and view areas around black holes in deep space, Arcand and Watzke show us all the important ways light impacts us. An introductory chapter describes what light is and how it behaves, while hundreds of full-color photographs and illustrations demonstrate concepts and make for a stunning book that's a joy to read and browse.
