Incoherent and Coherent superposition
Numéro d’image : 12032009
| Incoherent and coherent superposition. When two coherent waves of light are superimposed,the resulting intensity depends on the phases of both waves. Here a laser beam was spit into two beams that were then crossed at a small angle. Characteristic interference fringes were observed (bottom panel). For two incoherent waves,the total intensity is a sum of individual intensities. Here this was obtained by making a double exposure and blocking each beam one at a time (top panel) | |
