Title: Light, Dark, and the Electromagnetic Spectrum: A Look at Everything Light, Associated Phenomena, Uses of the Electromagnetic Spectrum and the History and Types of Illumination

Author: Scott Benjamin Gracie

Publisher: Tellwell

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.

EXCLUSIVE EXCERPT:

Why Things Appear Coloured

When white light hits a surface, some of the wavelengths of light are absorbed and some are reflected. The colour wavelength that gets reflected does so because the surface is the colour of that wavelength. For example, a red apple will absorb all the colours of white except for red, which it reflects. A green apple will absorb all the colours of white except for green, which it reflects. Objects will appear black under white light because they absorb all the colours of light.

This is a main reason why manufacturing good quality light sources is so important. Lighting manufacturers put the colours into the artificial light source and if one of the colours is slightly wrong, an object of that particular colour will not get its true colour reflected and will appear a different shade of the colour.

This reflection and absorption reaction of electromagnetic energy is the reason why darker coloured objects can appear hotter, as they are absorbing more electromagnetic energy rather than reflecting it away.

ABOUT THE AUTHOR:

Scott Benjamin Gracie's passion for light and the electromagnetic spectrum began in his early teens while tinkering with electronics as a hobby. He was formally introduced to the lighting industry while studying Electrical and Electronics in Sydney, Australia, and in 1998 he started his career making custom light fittings and lamps in his dad's garage. Formal lighting design qualifications expanded his opportunity to help project-manage and design on many industry levels.

Twenty-two years on, and Scott has worked on many major infrastructure, commercial and architectural lighting projects. He is a member of the Illuminating Engineering Society of Australia & New Zealand, the Colour Society of Australia, the International Dark Sky Association and the Astronomical Society of the Pacific.
