Interference with two sources
There are two wave sources on the left and a screen on the right.
-
The instantaneous intensity is drawn on a plane through the sources
and on the screen (on the right). If average is positive, the
third image displays the intensity averaged over average frames.
-
Unit length is equal to the distance between sources and screen.
-
On the left one can choose the amplitudes A1 and A2 of
both sources, their wavelengths λ1 and λ2, the
phase difference Δφ between them, and the phase velocity v.
-
One can also change the distance between sources a and whether
the latter are shown (fixed or oscillating).
