Electromagnetic Radiation
Electromagnetic radiation (EMR) is a form of energy that is generated by oscillating electric and magnetic fields. It is released in the form of waves and travels through air and space at the speed of light. EMR plays an important role in both everyday life and scientific investigations. Examples of uses include cell phone signals, X-rays, and radio and television broadcasts. In addition, EMR has been used in science to study the structure of atoms and molecules, in medical imaging to diagnose illnesses, in communication technologies for computers, phones, and televisions, and in climate science to study the effects of the Sun on Earth. Understanding the properties and behavior of EMR has allowed for the development of many important technologies and further investigations of the universe.
