红外线、紫外线分别是利用热作用和化学作用发现的,这些现象很难在课堂上演示。本探测仪能在课堂教学中进行演示实验,探测到红外线、紫外线的存在。 Infrared and ultraviolet light are discovered using heat and chemical effects, respectively. These phenomena are difficult to demonstrate in the classroom. The detector can perform demonstration experiments in classroom teaching and detect the presence of infrared rays and ultraviolet rays.
