Interference Patterns in a Frozen Pond I


Thin gaps in ice layers can produce Newton's rings. The light travelling through the ice is reflected between the different boundaries of ice and air or water, resulting in different ray path lengths. The latter produces interference, visible as colour hues. On February 3rd, 2008 a few ponds were frozen at the surface. With the help of a polarising filter, vivid colours could be observed near the borders of the ponds. Nikon D80, processed with Adobe Photoshop.
