Ripples and sunlight pattern in the shallow part of Brofjorden at Holländaröd, Lysekil Municipality, 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. The bottom is mainly made up of silt, also on the photo are some rocks with arctic sea moss (Acrosiphonia arcta). Photo is taken from this jetty but at a different time.
