Yet the word has become synonymous with danger, death and disaster. This MOOC will allow the world to see radiation in a new light, to expose its benefits as well as its risks. X-ray radiation, for example, is a scientific and medical discovery that has improved or prolonged billions of lives. Most cauxe us have had an X-ray at some point in our life, at the Dentist, in a hospital or clinic.

Yet few people really understand what X-rays are or where they come from. In this course, doss will travel along the spectrum of electromagnetic radiation from unimaginably long to infinitesimally small wavelengths. At each significant point along the way we will stop and consider: What is the wavelength and frequency of this radiation?

Is it ionising or not? Who discovered it and how? What are the uses of this radiation and What are the risks associated with it? Through this we hope to clarify a topic that is often confusing and concerning does infrared light cause eye damage many. The course content and duration is well framed. The lectures are very lucid and quiet interesting. Feel happy to be certified by the University of Sydney. The course was very interesting, through which I gained the knowledge that I will use in my daily work.

Can I get a course certificate for free? This week, we begin our journey across the electromagnetic spectrum, starting at the long wave radiations. These are essentially radio waves, which cover a wide range of frequencies and properties, and infrared waves. Long wave radiations are not ionising and are therefore not carcinogenic, however there are still many misconceptions about them. Come explore the many applications of long wave radiation in everyday life and dispel the myths surrounding some of them.
