Light, Dark, and the Electromagnetic Spectrum

by Scott Benjamin Gracie


GENRE:   Non-Fiction (Science / Physics)



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.



The Human Condition and Light Psychological Reactions

Most of us have a favourite colour and some colours are associated with different feelings and can evoke emotional responses.

Colours toward the red end of the electromagnetic spectrum, such as red, orange and yellow, are known as warm colours. These are generally associated with feelings of comfort or warmth.

Colours toward the blue end of the electromagnetic spectrum, such as green, blue and purple, are known as cool colours and can be sometimes associated with feelings of sadness, calm or indifference.

Coloured light research has shown a physiological change attributed to the hypothalamus. This part of the brain regulates hunger, sleep, body temperature and more.

The Colour of White Light and the Brain

The colour of white light can also affect the brain in many ways due to our body’s relationship with the Sun. White light can range from an orange ‘warm’ light, like from a candle, right through to very ‘cool’ white light that begins to look almost blueish.

Warm light is naturally relaxing and cool light naturally awakens our brain. This is why warmer light is used more in residential applications when we are supposed to be relaxed, and cool light is used in offices when we are supposed to be alert and awake.

This effect has been affecting the human body for hundreds of thousands of years with the rising of the ‘warm-coloured’ Sun when we are relaxed and awakening from sleep, the ‘cool blueish’ colour of the midday Sun and sky when we are alert and active, and then back to warm at sunset when we are beginning to relax and wind down to sleep.



Scott'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.
