A Leslie Cube is used to demonstrate that different surfaces emit different amounts of
infrared radiation.
Figure 3 shows an infrared detector and a Leslie Cube filled with hot water.

page 4.

0 2 . 6 The teacher improved the demonstration by using four infrared detectors connected to
a data logger and computer. Each detector was pointed at a different surface of the
Leslie Cube.
The distance between the surface and the detector was the same in each case.
Give two reasons why this improved the demonstration.
