In a double rainbow, however, a second reflection of light occurs within the water droplet. This additional reflection results in the formation of a secondary, fainter rainbow outside the primary one.

Imaging with TIRM To watch a droplet hit a surface and detect if there is any air between the drop and surface, the researchers used a technique called total internal reflection microscopy (TIRM).

Inside the water droplet, the light is reflected off the inner surface. This internal reflection causes the light to exit the droplet at a different angle, breaking the light into its full ...

Olina Bak, the founder of Drool Jewel, began creating her brand’s signature water-droplet jewelry out of homesickness for her native Greece, while she was abroad in London and it was raining.

The secondary rainbow is caused by a second reflection inside the droplet, and this “re-reflected” light exits the drop at a different angle (50° instead of 42° for the red primary bow).

Shining light on a water droplet creates effects analogous to what happens in an atom. This can help us understand how atoms work, write researchers.

A Leidenfrost droplet and its reflection over time, as the droplet shrinks down and flies away If you watch a skittering water droplet in slow motion, you'll realize there's one more puzzle---why do ...

The colored particles suspended in a water-in-oil droplet are driven to assemble into multiple structures, resulting in a reversible pixel switching performance in a controllable manner according ...

Secondary rainbows are fainter, too, since some of the light leaks out of the water droplet during the extra reflection and is lost to the air outside.

Atomic analogue: when a beam of light is shone into a water droplet, the light is trapped inside. (Courtesy: Javier Tello Marmolejo) Light waves confined in an evaporating water droplet provide a ...
