An experimental activity for teaching the origin of some bands of the electromagnetic spectrum using only one substance is presented. The activity is proposed for undergraduate students and focuses on developing their knowledge on the origin and the specific requirements for excitation and detection of three bands of the electromagnetic spectrum, in a comparative way. In this teaching approach, gamma rays from spontaneous emission of 40K, x-rays and visible radiation emission after appropriate excitation of KCl, is detected using instruments that can be found in an undergraduate physics and chemistry laboratory. The activity which combines demonstration and student engagement is described and the results related to the examination of each band are discussed.

使用 KCl 检查电磁波谱的某些波段的产生

介绍了一项仅使用一种物质教授电磁频谱某些波段起源的实验活动。该活动是为本科生提出的,重点是通过比较的方式培养他们对电磁波谱三个波段的激发和检测的起源和具体要求的知识。在这种教学方法中,使用可在本科物理和化学实验室中找到的仪器检测来自40 K自发发射的伽马射线、X 射线和在适当激发 KCl 后的可见辐射发射。描述了结合示范和学生参与的活动,并讨论了与每个乐队的考试相关的结果。
