41. When the same object is at a distance, less light energy is received by the eye. 42. Light energy enters the eye through the cornea, through the pupil and then through the lens.43. Photosynthesis converts light energy into chemical energy in the form of adenosine triphosphate ( ATP ). 44. Unlike electrons, the subatomic particles that make all things electronic possible, photons are packets of light energy . 45. This generates an electromotive force, and thus some of the light energy is converted into electric energy. 46. Therefore there is the potential for the absorption of excess light energy by photosynthetic light harvesting systems. 47. Photons ( light energy ) are generated within the nuclear reactions that fuel each and every star. 48. The waveguide analysis shows that the light energy in the fiber is not completely confined in the core. 49. Photovoltaic modules use light energy ( photons ) from the Sun to generate electricity through the photovoltaic effect. 50. In photosynthesis, carbon dioxide and water react in the presence of light energy to produce sugar and oxygen.
