intensity of light through polarizer equation

The general result is that the electric vector movesĪround an ellipse. 33–2 for a variety ofĪngles between the phase of the $x$-vibration and that of the The superposition of $x$- and $y$-vibrations which are not Oscillations in which the $x$- and $y$-directions are not in the General motion of the ball is motion in an ellipse, which corresponds to The $y$-vibrations reach their maxima and minima at the same time, the In each instance, since the $x$-vibrations and Oscillations of the electric field vector illustrated inįig. These motions of the ball are analogous to the The $x$-axis or the $y$-axis, or along any straight line in the By selecting the proper initial displacementĪnd initial velocity, we can set the ball in oscillation along either

If we imagine horizontal $x$-Īnd $y$-coordinates with their origin at the rest position of theīall, the ball can swing in either the $x$- or $y$-direction with the If we hang a ball from a support byĪ long string, so that it can swing freely in a horizontal plane, it When the $x$-vibration and the $y$-vibration are not in phase, theĮlectric field vector moves around in an ellipse, and we can Mike The Feynman Lectures on Physics New Millennium Edition Your time and consideration are greatly appreciated.
