[subtitle2]Stefan Boltzman Apparatus [/subtitle2]
Description:
- The apparatus is designed to determine the Stefan Boltzman 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.
Utilities Required:
- Electricity Supply : 1 Phase, 220 V AC, 2 kW.
- Table for set-up support.
