The apparatus is designedto determine the Stefan Boltzmann constant. The apparatus consists of ahemisphere fixed to a Bakelite plate, the outer surface of which forms thejacket to heat it. Hot water to heat the hemisphere is obtained form a hotwater tank, which is fixed above the hemisphere. The copper test disc isintroduced at the center of hemisphere. The temperatures of hemisphere and testdisc are measured with the help of temperature sensors.
Determination of StefanBoltzmann constant and study the effect of hemisphere temperature on it.
