Wave Interference QUICK PROBLEM

[clipperdude21]

1. Show the plot of the maxima and minima (ie:points of cons and dest. interference) for lamda= d/4, d and 2d





3. I am not quite sure what it is asking for. Do I just draw a graph that shows all 3 patterns?

Sounds like it. Just graph the points, connect them with a common curve (prob something like a sin or cosine graph) and point out where the curve reaches its maximum and/ or minimum (concave up or down).

could someone help me see how i draw the 3 graphs. I was just going to sketch a sin like graph followed by a sin graph with a phase then a 3rd graph with a larger phase.
