By what strange collision of images does this photo show the icicles hanging from the vines and wires of the backporch and reflections of the Tiffany-style lamp in the dressing room?
Light. Its reflection, refraction and the behavior of waves traveling along a rope or line, or vine, from a more dense medium - window glass - to a less dense medium (air, and vice versa) may be at issue here.
The wave doesn't just stop when it reaches the change of medium.
Rather, a wave will undergo certain behaviors when it encounters the end of the medium. Specifically, there will be some reflection off the boundary and some transmission into the new medium.
But what if the wave is traveling in a two-dimensional medium?
Or, what if the wave is traveling in a three-dimensional medium such as a sound wave or a light wave traveling through air? What types of behaviors can be expected of such two- and three-dimensional waves?
Who but a scientist - a physicist - could know?
Whatever the cause of the above strange and interrelative photo, it captures light inside and out, and ice in the same photo frame.
The photo of icicles below is more straightforward. Just ice on vines illumined by a string of light globes.
