12. Sometimes in the ocean a "rogue wave" will seemingly come out of nowhere, tower over small ships and quickly disappear. They can be quite dangerous. From what you have

done, explain in a sentence or two what might cause rogue waves. Extension 1: Set it on oscillate, high tension, no damping, slow motion and set the frequency to3 Hz. Will it make destructive interference? Constructive interference? Will the destructive ever reset allI balls to zero at the same time? Hint – let it run through at least 33 cycles. There isa marker on the camshaft that you can use to count them. Extension 2: Below is a Moire pattern. These patterns result from constructive and destructive interference between two different sources. Use your favorite mapping application, set it to satellite images, and navigate around a beach of your choice. Zoom in close enough to see the waves. Can you find interference patterns? You might have to look around some points, hooks-or even small islands. Attach a photo showing the interference pattern below. Extension 3: (Fun extra example, not graded) Moire patterns using two combs. Extension 4: (Fun extra example, not graded) Read about "Gravity Waves" which have several meanings. One is a kind of cloud produced from an atmospheric disturbance. They can propagate for hundreds of miles. Be sure to search for "Gravity Wave Images" so you can start watching for them in the sky. The second kind of gravity waves has to do with large interacting galactic bodies and are very strange and complex.
