Question

The arrows represent the x and y components of the electric field vector of a light wave at one point in time. 1. At each position on the z axis, add the x and y components graphically using a light pencil. Draw the resultant with dark pencil or ink. 2. Label which diagram represents linear polarization and which circular polarization. Is the circular polarization left or right? 3. For the circular polarization, what is the phase shift of the y component with respect to the x component? Answer in terms of the wavelength, e.g., ? = +?/4, ? = -?/2.

Explanation / Answer

1. You can join the points in the graph(i am unable to upload)

2. The first one is linear and the second figure is circular polaization since there is no phase difference of x and y components in the first figure and the second one has a 90 deg phase difference. The circular polarization is left handed since when we see the propagating wave, the components are rotating anticlockwise

3.It is a 90 deg phase difference i.e.,wavelength/4
