Document Summary
Light as a wave : c = fix. 5" m c : speed of a vacuum. * longer wavelength = lower frequency [ oscillates slower) monochromatic : light consisting of waves w/ same a coherent light : multiple light waves have same & produced at the same time. Lasers in coherent light : multiple light waves w/ different and /or produced at random times. Light bulb linearly polarized light : waves have electric and perpendicular magnetic field components vibrating in same plane. Formed by passing unpolarized light through polarizer (cid:8869) only allows waves in particular orientation through. 6. b) : range of wavelengths of light. Long wavelengths : helps transmit sound over long distances. Of continuous spectrum of sunlight (cid:8869) occur when raindrops act as prisms to refract light. * evidence for light behaving as a photon: balls hitting each other , then scatter apart as they transfer energy and momentum - acting as particles.
