The directed movement of a cell or organism away from a source of light. A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an electromagnetic radiation stimulus. Electromagnetic radiation is a propagating wave in space with electric and magnetic components. These components oscillate at right angles to each other and to the direction of propagation. The directed movement of a cell or organism towards a source of light. The directed movement of a motile cell or organism in response to an external stimulus. The directed movement of a motile cell or organism in response to light. The directed movement of a motile cell or organism in response to physical parameters involved in energy generation, such as light, oxygen, and oxidizable substrates. A change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a light stimulus, electromagnetic radiation of wavelengths classified as infrared, visible or ultraviolet light.
