Flash water ripple

Flash water ripple From Two Point Sources The diagrams on the last page show the interference between two waves in one dimensional space – along a line. When waves combine in two dimensions – over a surface, such as water waves in a ripple tank – or in three dimensions – such as where two loudspeakers radiate sound into 3D space – an interference pattern is created. Try to spot where constructive, and destructive, interference happens in the tank. Similar interference patterns are found for sound radiation from loudspeakers, but of course in this case you can’t see the ‘ripples’, you can only hear them.
