Can longitudinal wave be polarised?
No, the longitudinal wave can't be polarised. Because polarisation means lack of symmetry. But longitudinal waves are symmetrical from all the sides of vision. This is because their plane of propagation and vibration is same. this wave loks same from all the sides.
What waves can be polarised heat waves or sound wavesgive reason?
Any transverse waves can be polarised because the vibrations are confined to one plane. Therefore sound can be polarised. Because there is a position when the sounds plane of polarisation is at right angles to the polariser and no waves can pass through. Hope this helped may seem complicated now but believe me it will get easier :)
What are some uses of polarisation?
Polaroid filters in cameras and glasses; strain analysis (to measure the stress in objects such as seeing where the most stress occurs in a hip bone) and polarised radio waves are used for television transmission.
How can electromagnetic waves become polarised?
Through an atmosphere of Ozone, electromagnetic waves can become polarised.
Are light waves that oscillate only in a single plane polarized or unplaced?
'Polarised'.
What is polarising?
When a charged body is placed close to a nonconducting substance, the molecules of the substance get polarised. This is called polarisation.
How does a polarised anion differ from an unpolarised anion?
Well the difference will be in the type of bond formed as a result. The bond would be Ionic in case of polarized anion and Covalent in case or unpolarised anion.The related link below also talks about the size of the anion and charge density in determining the bond type.

Why horizontally polarised wave is used for mobile communication instead of vertically polarised wave?
For mobile, it's generally *not*. Most mobile comms need to be able to communincate in any direction, and horizontal polarisation tends to be directional in the horizontal (azimuth) plane. This means that horizontal polarisation is not preferred for mobile comms. You'll need to ask your question more exactly - what *kind* of mobile comms, for instance.

How do you identify isomers?
plane polarised light is being used. A solution of one enantiomer rotates the plane of polarisation in a clockwise direction. This enantiomer is known as the (+) form. A solution of the other enantiomer rotates the plane of polarisation in an anti-clockwise direction. This enantiomer is known as the (-) form. If the solutions are equally concentrated the amount of rotation caused by the two isomers is exactly the same - but in opposite directions. When optically active substances are made in the lab, they often occur as a 50/50 mixture of the two enantiomers. This is known as a racemic mixture or racemate. It has no effect on plane polarised light.
Uses of plane polarized light?
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.
Difference between monochromatic and polarized light?
Monochromatic means that it has only frequency. Polarized is definition for light which has its electric and magnetic vectors oscillating in a certain way (linearly polarized, elliptically and so on) but it might have many frequencies included. In the same time monochromatic light can be polarized.
How can electromagnetic waves become polarised?
Through an atmosphere of Ozone, electromagnetic waves can become polarised.
What are the different types of Ray Ban Lenses?
In China Polarised Ray ban is made of Plastic Lens. If not polarised,than be glass lens. Any way you may feel light when wearing polarised plastic lens and feel a little heavy in glass lens. But polarised is easy to be scratched. So should be careful when wearing . Hope this can help you !!
