1. S and S are the sources of coherent waves.

2. Water wave interference pattern shown is the result of constructive interference and destructive
interference occurs.
3. For ease of discussion, the wavefront of the crests is represented by a full line while the

wavefront of the troughs is represented by a dotted line as shown in the diagram on the next
page.
