If you missed today:
1. I had the ripple tank lab groups use the curved metal mirrors today. They first placed the concave side down and traced the shadow of the mirror and the obvious focal point when straight waves were sent. And then they flipped it to the convex side and sent one straight pulse at a time and tried to trace the reflected wave shadow on their paper and the curve of the convex side.
2. Then they went over to their seats and we drew the following two sketches using their drawings
concave sketch and convex sketch
