NOTE: There is a consistent “glitch” in the data at a polarization angle of about 40 and 140 degrees which is not entirely
explained by the non-linearity of the receiver. (This glitch is also present when the polarizer slits are used in part 5 of this lab.)
3. Continued rotation of the receiver results in duplications of the pattern above.
5.
6. The meter reading is zero when the polarizer slits are oriented vertically or horizontally. When the slits are at 45°, the
meter reads about 30% of its maximum value for that distance.
Answers to Questions
1. The meter reading more closely matches the intensity than it does the electric field.
2. The meter reading more closely matches the intensity than it does the electric field.
3. The polarizer transmits only the component of the wave parallel to the polarizer.
