hey guys this is pooja.....the answer is that it is used to detect the optical activity of a plane polarised light...!! my question: is polarisation of light by dichroism there in 2009 isc syllabus of physics.?? pls let me know...ok? thanks....do reply if u r reading my question....thanks...!! urs pooja
Hey Pooja. I might be able to help. :)
It is about the vibration be represented by a "sin" wave. Its unpolarised energy radiates from all direction. when plane polarized vibrate in a single plane of direction from the source.
Hope this helps.

What does Polarized light vibrates in?
For plane polarized light the electric vector of the light ray is allowed to vibrate in a single plane, producing a simple sine wave with a vibration direction lying in the plane of polarization - this is termed plane light or plane polarized light.
How can you obtain circularly polarized light from linearly polarized light?
Circularly polarized light is obtained by adding two plane polarized lights of same intensity that are orthogonal but with a phase difference of 90 degrees.
Would you expect a solution of a meso compound to rotate plane polarized light?
The meso compound, although it has sterogenic centers, is achiral. For this reason, it will not rotate plane polarized light.
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.
Explain how polarized light is different from non-polarized light.?
In polarized light, the plane of the electrical (and magnetic) oscillations is the same for all photons (particles of light). For example, if the light is traveling away from you, all photons might have electrical oscillations that go up and down.

Light waves that vibrate in only one plane are called what?
Light waves that vibrate in only one plane are called polarized.

What is Plane light?
A polarized light vibrating in a single plane perpendicular to the direction of propagation is called plane polarised light.
Would you expect a solution of a meso compound to rotate plane polarized light?
The meso compound, although it has sterogenic centers, is achiral. For this reason, it will not rotate plane polarized light.
What is it when all light waves vibrate in the same plane?
It's polarized light

Are light waves that oscillate only in a single plane polarized or unplaced?
'Polarised'.
What is a polarizer?
To begin, the correct term is "crossed" polarizer, not cross. The way that a crossed polarizer works is that it contains two polarizers, the first selects a plane of polarized light from an unpolarized light source (containing many oscillations, or planes). The second polarizer than absorbs that plane of polarized light that made it past the first, as it selects a plane of polarized light that is not the one let through the first.

What is plane polarized of light?
That's the simplest kind of polarization, and it simply means that all pieces of light - all photons - have the same orientation in space. For example, if the light shines horizontally, the light can be vertically polarized, or it may be horizontally polarized. Or at some other angle in between.
