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.
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.
What is vertical and horizontal polarization?
Light acts like both a particle and a wave. These particle-waves are oriented in random directions. Polarisation filters basically filter out the randomly oriented waves, and ensure that only light that is 'polarized' in a certain direction can pass through.Horizontal polarisation is when the light waves are oriented horizontally, and vertical is when the waves are vertical. The same princaple applies to the whole EM spectrum.
What filter can be used to filter sound waves of 50hertz from a signal?
notch filter
When you filter something what is the stuff inside the filter called?
Filtrate goes through the filter while the material trapped by the filter forms a cake...hence the name: Filter Cake.
What happened to light that is both vertically and hrizontally filtered?
If light passes first thorugh a vertical polarization filter, then through a horizontal polarization filter, hardly any light would get through at all.

Where is polarization used in real life?
Sunglasses and antennas to filter waves. Also the 3D glasses that you wear while watching a 3D movie, utilize polarization, to separate the images intended for your left eye and right eye.
What are the advantage and disadvantage of full wave rectifier with filtre?
either less ripple or ability to use smaller filter
What are the advantages and disadvantages of HVAC?
Advantage=no sweating Disadvantage=sweating
What are the advantages and disadvantages of electronics filter?
Electronic filters are used for distinguish the frequency spectrum of EM Wave. it can be high pass filter low pass filter or band pass filter or band stop filter. Advantage are they are higly sensitive to frequency ranges , they amplify the signal partially. and disadvantage is that the value or inductor and capacitor depend on the temperature so effective temperature can cause the change in frequency to passed by that filter.

Advantages and disadvantages of butterworth filter?
Advantage is that it has the most flat passband meaning that it is very good at simulating the passband of an ideal filter. The disadvantage is that it has a horrible stopband because it gradually goes to zero so some parts of the stopband are still passed. However, for an nth-order Butterworth Filter, as n increases, the closer it is to an ideal filter. However, it is highly impractical to build a ridiculously high order Butterworth filter.
How is 3d movies made?
There are several ways to make a film 3D: anaglyph images, polarization systems, what's known as the "eclipse method," the "Pulfrich effect," interference filter technology, spectral separation, lenticular printing, parallax barrier technology, and autostereoscopy
How do polarizing filters allow each eye to see separate images in the projection of three dimensional slides or movies?
A linear polarizing filter allows only light that is oriented a certain way to pass through.

What percentage of light is transmitted by two ideal Polaroids one on top of the other with their polarization axes aligned?
50% - If the light incident on the first filter is unpolarized then 50% of the light will be transmitted (see other questions for a full explanation of why). Next, when this 50% arrives at the second filter, Malus' Law says that if the axes match up, then 100% will be transmitted. 100% of 50% is 50%. :-)
