Leslie Cube Experiment: Physics Required Practical
Radiation & Absorption using a Leslie Cube: GCSE Physics Required Practicals
Investigating the amount of infrared radiation radiated from different surfaces.
In this practical you will:
- use a Leslie cube and infrared detector to compare the amount of infrared radiated from different surfaces: shiny black, matt black, shiny silver and matt white.
Method
- Put the Leslie cube onto the heat-proof mat.
- Fill the cube with very hot water and put the lid on the cube.
- Use the detector to measure the amount of infrared radiated from each surface. Make sure that the detector is the same distance from each surface.
Task
Plot an appropriate chart to show the amount of infrared radiated by each type of surface and write a conclusion.
