a. It is parallel to the direction of propagation and perpendicular to the direction of the electric field.
b. It is perpendicular to the direction of propagation and parallel to the direction of the electric field.
c. It is parallel to the directions of propagation and the electric field.

18. In an experiment, light is passed through two polarizing filters. The image below shows the first filter and axis of polarization.
Figure 27.58
The intensity of the resulting light (after the first filter) is recorded as I. Three configurations (at different angles) are set up for the second filter, and the intensity of light is recorded for each configuration. The results are shown in the table below:
Table 27.2
Complete the table by calculating θ1, θ2, and θ3.
