<p>There was a question 5 images, each with a point where waves were emitted and then it passed through a line, and the waves were changed. It asked which of the following would occur?</p>
<p>I put the one where the Waves emitted as ))) shapes, hit the line, and became |||||
There were two of those, I put the one where the ||| were closer together than the ))) becaus I think the refractive index for the 2nd part was greater.</p>
