From Bending to Reflection

Our study of iridescence in insect wings has made us wonder more about light so we have gone off at a tangent into mirrors.

We discovered that iridescence is caused by light being bent but mirrors work by light being bounced.

Anything with a smooth surface that reflects almost all of the light that hits it. It has to be smooth because rough surfaces scatter light instead of reflecting it.

When you see your face in a mirror you are seeing light from your face being bounced back or reflecting off the mirror.

Light travels through the glass and bounces off of the metal at the same angle to create a reflection.

Flat mirrors are the simplest form of mirrors. If you hinge two flat mirrors together they reflect each other's reflections.

Angling the mirrors in different ways creates some very beautiful patterns.

2 mirrors parallel to each other make an infinite number of reflections. Each image is the result of an image of an image, or an image of an image of an image or an image of an image of ... .

Try altering the angles of the mirrors in the Allen Centre...

Right angle mirrors will allow a maximum of two reflections of light from the object. But as the angle decreases, three, four, and even more reflections can occur.

Anamorphic pictures appear distorted to the naked eye.
When an anamorphic image is viewed from a special angle, or viewed

using a cylindrical mirror, the picture beomes recognizable.

Anamorphic Art Template
To make your own anamorphic artwork print out one of the grids from
the template link.

First draw your picture on the square grid.Match the coordinates of the picture on your square grid with those
on your polar grid. Reflect the polar grid image with a curved mirror to
discover your original image.
