Wave Interference
Physics 202, Lecture 9
1
When the disturbances from two sources combine the instantaneous am-plitudes add
Physics 202, Lecture 9
2
Reflection and refraction of waves provide a mechanical model for light andsound
Physics 202, Lecture 9
3
Reflection off a boundary acts as a second source that can produce standingwaves
Physics 202, Lecture 9
4
Three-dimensional standing waves are used to build microphones, antenna,and atoms
Physics 202, Lecture 9
5
Double slit experiment provides definitive evidence for the wave nature oflight
Physics 202, Lecture 9
6
Single slit diffraction can be understood as the interference of a series ofsingle sources
Physics 202, Lecture 9
7
Iridescence in nature is usually from thin-film interference
