Iridescence Day

Iridescence Day

Iridescence is a spectacular effect found in natural and artificial materials and in atmospheric effects on light.

It is defined by the reflectance of multiple colours from the same material (which may be solid, liquid or gas) and a change in the hue and intensity of the reflected light with a change in the angle of viewing or of illumination. It is caused by multiple physical phenomena, and its consequences in biological, psychological and engineering contexts remains to be fully understood.

We will be hosting four speakers on the subject of Iridescence. The talks will be for a general audience, and are intended to bring together radically different perspectives on iridescence.
