If the light is “monochromatic” (one color or wavelength, like a laser), then this leads to dark areas. In that case the thickness of the film tends to change rapidly, which is why the colors in soap films tend to swirl and change so fast. In addition to light’s waviness, it also has polarization (which is a fundamentally not-particle thing to have).

The amount of light that reflects off of a surface depends on the polarization of that light, which is why polarized glasses are sold to drivers to cut down on glare.

It’s a long way from obvious (there’s It looks like the sunlight is made of particles moving in straight lines, but in reality you don’t need “particleness” to describe what’s happening here. With enough elbow room, waves will proceed in a straight line due to interference effects., absolutely everything is fundamentally quantum mechanical. The De Broglie wavelength decreases with increasing mass, and while even the lightest particles have fantastically small wavelengths (electrons typically have wavelengths on the order of trillionths of a meter), light can have wavelengths ranging up to miles long (radio waves).

The gaps in the door are very large compared to the wavelength of the light (approx. What we consider to be “classical mechanics” is just a special case of quantum mechanics (a large-scale, non-coherent case). Observing quantum effects in matter is difficult, but we see it in light so much that we think it’s normal (which it is, I suppose). absolutely everything, what follows are some distinctly wavy and quantumy things that you might come across while palling around on this big blue world.

So, if you hold up a horizontal polarizer below the Sun it’ll appear clear, but if you hold it up by the side of the Sun it’ll appear dark (bottom).

Because of the way light scatters in air, if you point your hand at any point in the sky (other than the Sun), and turn your palm toward the Sun, then the flat of your hand will be aligned with the polarization of the light coming from that part of the sky.

Some light will bounce off of the surface of the film, and some will go through.
