In 1940, the Tacoma Narrows Bridge across the Puget Sound collapsed. The bridge was a suspension bridge. The wind blowing through the narrows matched the natural frequency of the bridge. This resulted in a large movement of roadway, which eventually caused the bridge to fail.
A
absorption, because the bridge absorbed all the energy of the windB
diffraction, because the wind moved around the bridge, which set the bridge into motionC
interference, because constructive interference occurred when the wind frequency matched the natural frequency of the bridgeD
interference, because destructive interference occurred when the wind frequency matched the natural frequency of the bridge
