  2. Rainbow - Wikipedia

    en.wikipedia.org/wiki/Rainbow

    A reflection rainbow may be produced where sunlight reflects off a body of water before reaching the raindrops, if the water body is large, quiet over its entire surface, and close to the rain curtain. The reflection rainbow appears above the horizon.

  3. Reflets dans l'eau - Wikipedia

    en.wikipedia.org/wiki/Reflets_dans_l'eau

    Writing "images", Debussy was purposely intending not to create linear musical progression, but a sonic representation of water. Reflets dans l'eau is also an example of the new tone colors Debussy discovered for the piano in this part of his life, and although he later refined this style, it is representative of a major breakthrough in piano ...

  4. Backscatter (photography) - Wikipedia

    en.wikipedia.org/wiki/Backscatter_(photography)

    In photography, backscatter (also called near-camera reflection [1]) is an optical phenomenon resulting in typically circular artifacts on an image, due to the camera's flash being reflected from unfocused motes of dust, water droplets, or other particles in the air or water.

    Water vapor concentration for this gas mixture is 0.4%. Water vapor is a greenhouse gas in the Earth's atmosphere, responsible for 70% of the known absorption of incoming sunlight, particularly in the infrared region, and about 60% of the atmospheric absorption of thermal radiation by the Earth known as the greenhouse effect.

  7. Ripple tank - Wikipedia

    The angle of incidence and angle of reflection will be the same. If a concave parabolic obstacle is used, a plane wave pulse will converge on a point after reflection. This point is the focal point of the mirror. Circular waves can be produced by dropping a single drop of water into the ripple tank.

    Monocular diplopia (or polyplopia) from reflections at boundaries between the various ocular media; Phosphenes from stimulation other than by light (e.g., mechanical, electrical) of the rod cells and cones of the eye or of other neurons of the visual system; Purkinje images.
