For Young’s double-slit interference,
ure 1) easily allows you to alter all the
variables in the equation – wavelength ,
λ, slit separation, d, slit–screen distance,
L, and see the resulting fringe separation. On the same topic, one that the pupils
seem to like (figure 2) is www.colorado.

Understanding the concept of resolving power in the Fabry–Perot interferometer using a digital simulation
It is defined as the ratio of the wavelength of the source λ
to the minimum difference of wavelengths λ that generates two circle series that can be
discriminated. Our experience in teaching optics to second year university physics students shows that
the explanation of the … Because of this reason,
we propose to use a Java applet to show how the Fabry–Perot interferometer …
