The figure shows polarized light meeting one ideal polarizer. What passes through the filter?

Use the figure of a polarized wave and an ideal polarizer. What emerges from the filter?

The figure shows horizontally polarized light reaching a polarizer whose axis is tilted. What best describes the output?

In the figure, polarized light meets an ideal polarizer. Which result is correct?

Use the figure to predict the beam after the ideal polarizer. What happens?

The figure gives the angle between two ideal polarizer axes. Unpolarized light of intensity $600\text{W}/{\text{m}}^2$ enters the first filter. What intensity leaves the second?

Use the angle shown between two polarizer axes. If unpolarized light of $800\text{W}/{\text{m}}^2$ enters the first filter, what intensity emerges from the second?

The angle shown is between two ideal polarizer axes. Unpolarized light of intensity $500\text{W}/{\text{m}}^2$ enters the first filter. What intensity leaves the second?

Light already polarized vertically has intensity $900\text{W}/{\text{m}}^2$ and passes through a polarizer whose axis is 45.0 degrees from vertical. What intensity emerges?

Unpolarized light of intensity $1000\text{W}/{\text{m}}^2$ passes through a vertical polarizer and then a second polarizer 60.0 degrees from vertical. What intensity leaves the second?

A beam already polarized along 0.0 degrees has intensity $120\text{W}/{\text{m}}^2$. It enters an ideal polarizer with axis 30.0 degrees from that direction. What intensity is transmitted?

Unpolarized light of intensity $640\text{W}/{\text{m}}^2$ passes through one ideal polarizer. What is the transmitted intensity?

Light already polarized parallel to a reference line has intensity $500\text{W}/{\text{m}}^2$. It passes through a polarizer whose axis is 75.0 degrees from that line. Round the transmitted intensity to the nearest $W/m^2$.

Which statement best describes polarization of light?

Why can a transverse rope wave be polarized but sound traveling through air cannot?

In $I=I_0{\cos }^2(\theta )$ for a polarizer, what does theta represent?

Unpolarized light passes through one ideal vertical polarizer. Which describes the emerging light?

Glare reflected from a wet road is largely horizontally polarized. How should a driver's polarizing sunglasses be oriented to reduce that glare?

A photographer wants to reduce reflections from a lake while seeing rocks below the surface. What should she do with a polarizing filter?

In a polarized 3-D movie, why can the glasses send a different image to each eye?
