Description

The experiment P3.7.4.2 deals with the absorption of microwaves. Working on the assumption that reflections may be ignored, the absorption in different materials is calculated using both the incident and the transmitted intensity. This experiment reveals a fact which has had a profound impact on modern cooking: microwaves are absorbed particularly intensively by water.
