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 wind
B
diffraction, because the wind moved around the bridge, which set the bridge into motion
C
interference, because constructive interference occurred when the wind frequency matched the natural frequency of the bridge
D
interference, because destructive interference occurred when the wind frequency matched the natural frequency of the bridge

B
refraction, because the light bends through the clouds
C
absorption, because the sunlight is absorbed by the clouds
D
