Polarization of Light Practice Problems

Vocab-style flashcards based on lecture note calculations and concepts regarding light polarization, Malus's Law, and filter angles.

Original intensity of unpolarized light ($I_0$) when transmitted intensity after a vertical polarizer and an analyzer at $60^\circ$ is $18\,\text{W/m}^2$

$$144\,\text{W/m}^2$$

Intensity emerging from Polarizer 1 with an angle between polarizers of $45^\circ$ and an output intensity from Polarizer 2 of $180\,\text{W/m}^2$

$$360\,\text{W/m}^2$$

Angle required between the direction of polarized light and the axis of a polarizing filter to reduce its intensity by $90\%$

$$71.6^\circ$$

The angle between a polarizer and analyzer that results in blocking all light

$$90^\circ$$

Percentage of light intensity that passes through two polarizing filters with axes placed at $90^\circ$ to each other

$$0\%$$

Percentage of light intensity that passes through two polarizing filters with axes placed at $45^\circ$ to each other

$$50\%$$
