Polarization of Light

The angle at which the intensity of transmitted light becomes maximum when a polarising sheet is rotated between two crossed polaroids is
[$\theta$ is the angle between transmission axes of first and middle polaroid]

Light, from a sodium lamp, is passed through two Polaroid sheets,  $P_1$  and  $P_2$  kept one after the other. Keeping  $P_1$  fixed,  $P_2$  is rotated so that its ‘pass – axis’ can be at different angles, $\theta$  with respect to the pass – axis of $P_1$ .

An experimentalist records the following data for the intensity of light coming out of  $P_2$  as a function of the angle $\theta$ .

$[I_0$  = Intensity of beam falling on  $P_1]$

One of these observations is not in agreement with the expected theoretical variation of I. Identify this observation.

Two polaroids are set in crossed positions. A third polariser is placed between the two making an angle $\theta$ with the pass axis of the first polaroid. In what orientations(of third polaroid with respect to first polaroid) will the transmitted intensity be (i) minimum and (ii) maximum?

How is a light wave a transverse wave?

A sound wave is a transverse wave.

A sound wave is a pressure wave; they can be thought of as fluctuations in pressure with respect to time.
