"Constructive Oar Destructive Interference?"
As droplets of water trickle off the oars in this photograph, waves are created in the lake. When these waves come together, they interfere with each other. A property called constructive interference occurs when the waves add together to make a larger wave, but only if both waves come together in the same orientation. The crests of the waves must be equal in height when they interfere in order to produce the larger wave However, destructive interference occurs if the if the waves come together in opposite orientation, with one crest up and the other down. In destructive interference, if the magnitude of the two waves are equal, then the waves cancel out, a phenomenon that results in no waves.
The distance between the two droplets affects the amount of interference that occurs. When the oars are closer together, the constructive and destructive patterns are wider apart because less interference is occurring. When the oars are further apart, more interference occurs. These type of interferences also occur in light and sound waves.

I drove past this place two days ago and nearly got into a car accident because I was checking it out and not looking ahead of me. (My son said, "Woo, adrenaline rush! Feels good!") Went back the next day to get a shot of it.
Garden Grove, CA.
Humber Bridge north tower at dusk. I mis-timed the car going by, but in fact it worked better - some of my other shots had no light in the bottom right and it just makes a big black dead space, the light from the headlights just picks out the road and helps give it a tiny bit of form. Another shot with the headlights in was just too much, and the shutter speed wasn't slow enough to make trails, so I liked this one best.
The beginning of 'constructive' tipping to form the terracing at the Rooley Avenue end of the stadium.
Showing the progress of the development of Odsal Stadium in late August and early September 1935. Note the dustbin wagon unloading!
