In light reactions‚ the goal is to transfer solar kinetic energy to chemical potential energy. This is first done by the absorption of a photon of light. Plant pigments are molecules that selectively absorb light energy at wavelengths. A pigment molecule absorbs a photon of light one of pigments electrons jumps to an energy level further than the nucleus. The electron has more potential energy here. The electron now has raised from the ground state to an excited state. Pigments of photosynthesis

You notice that there is an absence of light. In the same way‚ when we judge someone to be‚ in essence‚ evil‚ that is just how we perceive it

Xxx.comTheories of light In the seventeenth century two rival theories of the nature of light were proposed‚ the wave theory and the corpuscular theory. The Dutch astronomer Huygens (1629-1695) proposed a wave theory of light. He believed that light was a longitudinal wave‚ and that this wave was propagated through a material called the ’aether’. Since light can pass through a vacuum and travels very fast Huygens had to propose some rather strange properties for the aether: for example; it must
