Document Summary
Particle nature of light particles (the corpuscular theory) Isaac newton was the first person to propose that light is composed of small. If we shine a light source on a solar cell, the cell generate electricity. The different colors of light represent different particles. The light knocks electrons out of the silicon atoms in the solar cell. The free electrons can wander around the circuit generating electric currents. 1678: dutch physicist christaan huygens proposed that light travels in waves. 1801: english physicist thomas young clearly demonstrated the wave nature of light by passing light through two thin slits. Instead of producing two bright spots, the slits produced a series of alternating bright and dark bands, an interference pattern caused by the wave nature of light. An electric field (or force) is generated by a charged particle. He found that a pattern of alternating electric and magnetic fields would. A magnetic field is generated by moving charges (changing electric fields)
