Absorbent and emitting powers apparatus
Product Code : SCL-MH-12808
The Absorbent and Emitting Powers Apparatus by Educational Instrument India is a physics laboratory instrument designed to demonstrate how different surfaces absorb and emit heat radiation. It is ideal for studying thermal radiation, heat absorption, heat emission, surface color effects, and basic thermodynamics.
This apparatus helps students understand that black, dull, polished, and shiny surfaces do not absorb or emit heat at the same rate. Through practical observation, learners can compare the thermal behavior of different surfaces and understand why dark surfaces are good absorbers and emitters, while polished surfaces are poor absorbers and emitters.
The Absorbent and Emitting Powers Apparatus is suitable for school physics laboratories, college practicals, heat transfer experiments, and classroom demonstrations. It is built with durable laboratory-grade components for repeated academic use under proper supervision.
