The Electromagnetic Wave
This program shows an electromagnetic wave with
linear or circular polarization and the effect of an analyzer (Polaroid film).
In the coming upgrade, version 1.1 submitted to
Apple Store , a “help button” will be included giving
the meaning of each button + a few pages of explanations (screens below).
Buttons in version 1.0:
Study:
An electromagnetic wave has its E field always
perpendicular to the B field and the propagation of the wave is in the
direction of the vector product E x B. Check those properties on the animation.
Because the analyzer transmits the component of
the incident E field parallel to its axis, check that it will transmit 100 % of
the wave in the case of a linearly polarized incident wave if E is parallel to the
polarizer axis but will stop the wave if E is perpendicular to the polarizer
axis.
Hence, a circularly incident wave can never be
stopped by the polarizer.
