The Science Behind the Iridescent Colors of Butterfly Wings
TLDR Butterfly wings have a shimmery, color-changing quality called iridescence, which is different from ordinary pigment. This is due to the reflection of light from the top and bottom surfaces of the wings, resulting in constructive interference and the creation of iridescence.
Timestamped Summary
00:00
Butterfly wings are iridescent due to the shimmery color-changing quality called iridescence, which is different from ordinary pigment.
04:04
Iridescence is a super spectacular reflection of color that changes depending on the observer's perspective, and it is different from ordinary pigments.
07:42
When light is reflected from the top and bottom surfaces of an object and the phases of the waves match up, it results in constructive interference and creates iridescence.
11:46
When white light hits a multi-layered transparent object, such as a bubble, the light that reflects off the top and bottom surfaces can be in phase with each other, resulting in amplification and the creation of iridescence.
15:28
Butterfly wings appear striking because they have many layers stacked on top of each other, allowing for more chances for light to reflect back in phase and create iridescence.
19:28
Butterfly wings have delicate scales that can disintegrate into powder when touched, and while touching a butterfly wing may not kill it, breaking the veins connecting the wings will likely result in the butterfly's death.

To learn more about butterfly wings and their striking colors, you can search for "butterflies striking colors" on the How Stuff Works website.

The hosts thank various people for their contributions to the podcast and then read a listener mail from a teacher who uses the podcast to teach writing to inmates in a Virginia prison.
