Synopsis: |
Light is strange, sometimes dazzling, sometimes dim. It can be coloured or white, and also invisible. It has incredible energy, and zooms at amazing speeds. But what it actually is, no one, not even the most eminent scientist, can say. This book explains where light comes from and how humans have found many different ways of making it, the most sophisticated being the laser. The book is part of a series of illustrated science texts for children, teenagers and families. The authors are scientists who are prominent in their fields and have an interest in furthering the public understanding of science. |
