Description: What is being referred to when people speak of "radiation"? How is radiation produced? Have you ever noticed how a straw can look bent when you see it in a glass? What causes this, and how do scientists use this effect? This course explains that radiation is a form of energy, how to measure its intensity, where it comes from and how different bands of energy can be separated and identified. It includes practical applications such as determining the amount of energy available from sunlight and building a simple spectroscope to study the radiation from different chemicals.
