Unpolarized light is incident on a combination of a polarizer, a /2 pl...
Configuration 1: Axes of the polarizer, the /2 plate, and the /4 plate are all parallel to each other.

In this configuration, all the elements are aligned in the same direction. Let's analyze the effect of each element:

1. Polarizer: The polarizer only allows light with a specific polarization direction to pass through. Since the incident light is unpolarized, the polarizer will convert it into linearly polarized light with a specific polarization direction determined by the polarizer's axis. Therefore, the output polarization is linear.

2. /2 Plate: A /2 plate introduces a phase difference of half a wavelength between the two orthogonal polarization components. However, since the incident light is already linearly polarized, the /2 plate will not affect the polarization state. Therefore, the output polarization remains linear.

3. /4 Plate: A /4 plate introduces a phase difference of a quarter of a wavelength between the two orthogonal polarization components. Again, since the incident light is already linearly polarized, the /4 plate will not affect the polarization state. Therefore, the output polarization remains linear.

Hence, in configuration 1, the output polarization is linear.

Configuration 2: The /2 plate is rotated by 45° with respect to configuration 1.

In this configuration, the /2 plate is rotated by 45°. Let's analyze the effect of each element:

1. Polarizer: Same as configuration 1, the polarizer will convert the unpolarized light into linearly polarized light.

2. /2 Plate: The /2 plate introduces a phase difference of half a wavelength between the two orthogonal polarization components. Since the /2 plate is rotated by 45°, the incident linearly polarized light will be split equally into two orthogonal linearly polarized components. Therefore, the output polarization is circular.

3. /4 Plate: Same as configuration 1, the /4 plate will not affect the polarization state.

Hence, in configuration 2, the output polarization is circular.

Configuration 3: The /4 plate is rotated by 45° with respect to configuration 1.

In this configuration, the /4 plate is rotated by 45°. Let's analyze the effect of each element:

1. Polarizer: Same as configuration 1, the polarizer will convert the unpolarized light into linearly polarized light.

2. /2 Plate: Same as configuration 1, the /2 plate will not affect the polarization state.

3. /4 Plate: The /4 plate introduces a phase difference of a quarter of a wavelength between the two orthogonal polarization components. Since the /4 plate is rotated by 45°, the incident linearly polarized light will be split equally into two orthogonal linearly polarized components, but with a phase difference of a quarter of a wavelength. Therefore, the output polarization is circular.

Hence, in configuration 3, the output polarization is circular.

Therefore, the correct answer is option A: Linear for configuration 1, linear for configuration 2, circular for configuration 3.
