About Stefan Boltzmanns Apparatus
DESCRIPTION :- The apparatus is designed to determine the Stefan Boltzmann constant. The apparatus consists of a hemisphere fixed to a Bakelite plate, the outer surface of which forms the jacket to heat it. Hot water to heat the hemisphere is obtained form a hot water tank, which is fixed above the hemisphere. The copper test disc is introduced at the center of hemisphere. The temperatures of hemisphere and test disc are measured with the help of temperature sensors.
EXPERIMENTATION :-
Determination of Stefan Boltzmann constant and study the effect of hemisphere temperature on it.
Precise Laboratory DemonstrationsThis apparatus enables precise demonstrations of thermal radiation principles, including direct observation of energy differences between black and white metal surfaces. Its robust build and reliable voltage operation make it ideal for repetitive experiments and academic investigations.
Versatile Assortment SetThe assortment set provides both white and black metal surfaces, allowing comparative analysis during experiments. This versatility is particularly useful for demonstrating the influence of color and material on heat absorption and emission in educational settings.
