Science

From smartphones to microwaves, invisible forms of light have a profound effect on our lives. This popular science book explains what they are, how they work and how they have been put to work in modern technology.

The light penetrating our eyes, an incoming call on a mobile phone, or an X-ray at the dentist: all are different kinds of light, or electromagnetic radiation. This illustrated guide to the electromagnetic spectrum explores the nature of light wavelength by wavelength – radio waves, microwaves, infrared, visible light, ultraviolet, X-rays and gamma-rays – revealing the properties, characteristics and practical applications of each type of radiation with incisive explanations, diagrams and hundreds of full-colour photographs.
