Hi all! I would like to ask you something about the experiments at IAL physics unit 3. In the specification booklet of edexcel it is written "Demonstration of slow speed of ion
movement during current flow" and "Demonstration using a ripple tank or computer simulation" and some other like these. First of all, what does it mean "demonstrate"? Should someone know the apparatus and the analysis of the experiment? WHy in other experiments it says "Measure"? For example "Measure the emf and internal resistance of a cell, e.g. a solar cell". Is it the same as "demonstrate"? Also, where can I find the ripple tank and current flow experiments? Thanks in advance?
