Heat Transfer - Radiation _ GCSE Physics

The video tutorial explains how heat is transferred through conduction, convection, and radiation, with a focus on radiation. It describes how all objects emit and absorb infrared radiation, which can be detected by thermal imaging cameras. The tutorial highlights that radiation can travel through space, unlike conduction and convection. It also discusses how different surfaces interact with infrared radiation, with dark, matte surfaces being good absorbers and emitters, while shiny surfaces are good reflectors, as seen in thermoses.
