Answer: A sheet that is optically anisotropic.
Answer: "Film" means that it is a thin layer "polarizing" means that it polarizes light that goes through it. For example, if you shine unpolarized light on it, light will get out on the other side - polarized in a certain orientation.

What is a zone of polarizing activity?
A zone of polarizing activity is a region of connective tissue which carries instructions which direct the developing limb bud to form along the anterior-posterior axis.
How do you polarize a beam of light?
Polarizing a beam of light is simply accomplished by passing the light through a polarizing filter. The polarizing filter will permit only light of a given polarization (or polarity) to pass through it. There are several different types of polarization, but they affect similar results. Use the links and check out the pictures.
What light rays do all the different color polarized lenses block or attenuate?
Polarizing filters are not necessarily color filters. A polarizing filter may also includea color dye, but that's not its purpose.-- All filters attenuate all light rays to some degree.-- A polarizing filter, in principle, attenuates all colors equally, by blocking any lightwhose 'E' field is not parallel to the polarizing direction of the filter, regardless ofwavelength.-- A color filter, in principle, blocks all colors except those in a narrow range of wavelengths.The only wavelength it doesn't block is the color you see coming out of it.
Which phenomenon causes polarization of light?
Light is usually unpolarized, it becomes polarized when it passes through a polarizing filter. Light can be polarized because it travels as a transverse wave (of oscillating electric and magnetic fields) orthogonally to the direction of the medium in all directions, and polarizing filters polarize light in one plane. Polarized filters in the vertical plane only allow light in the vertical plane to pass through. Ex. polarized sunglasses have a polarizing filter in the vertical plane in order to minimize glare which is polarized light in the horizontal plane. and yes polarizing filters can be rotated to polarize light in other planes as well.
How can neurotransmitters inhibit or excite a postsynaptic neurons?
Inhibit it by hyper polarizing the membrane or excite it by bringing the voltage closer to the threshold potential.
What happen when light passes through a polarizing filter?
It is called polarizing chemical change
What is directional protection relay and how is it works?
Directionalized relays are relays that use a polarizing circuit to determine which "direction" (in the zone of protection, or out of the zone protection) a fault is. There are many different types and different polarizing methods - ground polarizing, voltage polarizing, zero sequence voltage polarizing, negative sequence polarizing, etc. The basic operation of this relay is just like any nondirectional relay, but with an added torque control - the directionalizing element. This element allows the relay to operate when it is satisfied that the fault is within the zone of protection (ie not behind where the relay is looking).
What is PBS in optics?
polarizing beam splitter
Who were some people who invented technology?
Otis invented important parts of an elevator, making them safe.Land invented a very useful film for polarizing light waves.Daimler made important contributions to the motor car.
How can two polarizing filters be used to show that has some properties of a wave?
If one polarizing filter is angled 90 degrees from the other, they will block all light.
What is the process of mapping a magnetic disk's surface?
Polarizing

What is the light that passes through a polarizing filter?
Polarised light!
Is a polarizing filter the same as a haze filter?
A haze filter, typically an 81A or 81B Wratten-type filter is used to cut down the amount of ultraviolet light entering the camera's optics. You can use this instead of a clear glass filter to protect the front element of your camera lens. There are two types of polarizing filters - linear and circular. Depending on your type of camera (film versus digital), you may need to use a circular polarizer to be able to see through the lens system. Polarizers cut down the amount of light entering the lens by acting like a set of Venetian blinds and letting light only come in as a single plane. There is more information on polarizing filters in the question In photography what does a polarizing filter do?
How can two polarizing block all light passing through them?
Polarizing materials block light except in a specific direction. Two of these materials in opposite directions let no light through (it is absorbed).
Which of the following are used for studying rocks with a polarizing microscope?
Thin sections.
