Report

I believe there is a problem with cards 2 and 3. The properties of constructive and destructive waves have been mixed up. See The New Wider World by David Waugh pg 300; Edexcel IGCSE Geography Student Book by Michael Witherick & Steve Milner pg 34 for correct definitions and properties. However , the diagram on pg 34 of the latter text has been mislabeled hence leading to confusion.
