The unit has been designed to demonstrate the fundamental laws relating to radiation. By performing a series of simple experiments the students may verify the relevant equation appropriate the behavior of radiations. Thermal radiation is a mode of heat transfer which differs significantly from the other two modes. The fact that radiant energy transfer occurs across a vacuum is often disturbing to students unless the theory relating to properties of electromagnetic waves has been presented.
The engineer is not directly concerned with the mechanism by which heat transfer occurs, but a sound knowledge of the properties and laws relating to the topic are required. By performing a series of simple experiments the student may verify the relevant equations of radiation. The unit Thermal Radiation consists of electrically heated radiant heat and light sources together with a comprehensive range of targets and measuring instruments.
