of waves of unequal frequencies (formation of Beats)
When waves are coming out
from he two sources, a blue cross appears in the interference pattern. This
is the observation point, the two waves arriving there and the combined resultant
are displayed on the right hand side.
observation point is draggable to move.
right hand side, the waveform of "wave I" is draggable to move up
The grey lines appearing in the interference pattern are
the nodal lines, along which destructive interferences take place.
