Light up My Life
Kellett, Sarah
Teaching Science, v61 n3 p10-13 Sep 2015
Simply stated, light is nature's way of transferring energy through space. Discussions of light usually refer to visible light, which is perceived by the human eye and is responsible for the sense of sight. We see however, only a small part of the light spectrum. Light connects us as we sit and tell yarns around camp fires. Yet, one in every four people in the world lives without electricity. To answer this world-wide deficit, the United Nations announced 2015 to be the International Year of Light and Light-based Technologies. This article presents a discussion of the basics of light, how it can be produced, how it travels, and how it can be both seen and unseen. With the help of technology, invisible light can reveal certain things that are normally hidden from our eyes in the form of microwaves or X-rays. Today, with new and improved light technologies--such as optical fibres, radio telescopes, and X-ray detectors--we can explore and connect the nations of the world like never before.
