Ripples dispersing sunlight into underwater rainbows in Brofjorden.jpg

Ripples and sunlight pattern in the shallow part of Brofjorden at Holländaröd, Sweden. Under some conditions (clear water, angle of sunlight, size of ripples, depth of water) the ripples acts like prisms dispersing the sunlight into small underwater rainbows projected on the bottom. At the same time some of the other ripples becomes "magnifying glasses" and enlarge the small rainbows.
