A Polarizing filter is used to reduce glare on reflective surfaces including glass, windows, and water.

A polarizer is used to:

light waves can be polarized as they are:

Polarization of light can be done by:

Properties of waves are

I. polarization

II. diffraction

III. refraction

Which of these properties apply to sound waves?

Approximately how much light is blocked by two polarizing filters that are perpendicular to each other?

Approximately how much light is blocked by two polarizing filters that are parallel to each other?

Approximately how much light is blocked by a single polarizing filter?

Polarized light of intensity I₀ is incident on a polarising filter. The angle between the plane of polarisation of the incident light and the transmission plane of the polariser is θ. Which graph shows how the intensity I of the light transmitted through the polariser varies with θ?

Unpolarised light of intensity I₀ is incident on a polariser with a vertical transmission axis. The transmitted light is incident on a sheet of material X. After transmission through X the intensity of the light is I₀/2.

It is suggested that X could be

I. a polarizer with vertical transmission axis

II. a polarizer with horizontal transmission axis

III. non polarizing glass.

Which of the above suggestions is/are correct?

Two polarizing filters are set up so the transmitted light is at a maximum intensity.

Through which angle should polariser 2 be rotated so that no light is transmitted?

which picture shows the polarization of light :

If a polarizer is placed in a beam of nonpolarized light, only the components of the waves in the .......................direction as the polarizing axis can pass through .

? If the polarizing axis of the second filter is parallel to

that of the first, the light will .............
