Ed WiebeTwo photos of the same male Anna’s hummingbird. The photos were one second apart. The feathers’ iridescence is structural, not from dyes. It’s caused by layers of tiny granules of melanin in the feather barbules. The melanin is dark brown or black. The structure of the granules results in the nearly specular reflection of narrow wavelength bands of light and the absorption of other colours.

j_bertolotti<a href="https://mathstodon.xyz/tags/PhysicsFactlet" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PhysicsFactlet</a> It's a foggy day here in Albion, so let's talk about light (multiple) scattering! Fog is composed of micrometre sized water droplet that can scatter light. This has two main effects: some of the light that was supposed to reach your eyes don't (because it is scattered away), and some of the light that was not supposed to reach you gets scattered into your eyes. The denser is the fog and the further an object is from you, the more likely light is to be scattered away before it reaches your eyes. The amount of unscattered light (i.e. the one your eyes can use to form a sharp image) goes down exponentially (Lambert-Beer law), so an object in the fog gets dimmer pretty quickly. On the other hand there is a chance that light that was never meant to reach you is now scattered into your eyes, but since it arrives from a largely random direction, mixed up with a lot of other scattered light, your brain perceived it as a white blur on top of everything else. And since far away object were already dim, this white halo can easily overpower them, so you can't see them anymore.<a href="https://mathstodon.xyz/tags/Physics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Physics</a> <a href="https://mathstodon.xyz/tags/Optics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Optics</a> <a href="https://mathstodon.xyz/tags/ITeachPhysics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ITeachPhysics</a> <a href="https://mathstodon.xyz/tags/EverydayPhysics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EverydayPhysics</a>
