Wave Interference

Physics 202, Lecture 9

1

When the disturbances from two sources combine the instantaneous am-plitudes add

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

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
