What is the Difference between polarized light and ordinary light?

Answer 1

unpolarized light = light waves vibrate in more than one plane

Polarized light = vibrations of light waves occur in a single plane.

Answer 2

There are two types of waves A.Transverse wave, B.Longitudinal Waves. In a Longitudinal wave the particle displacement is parallel to the direction of wave propagation.Eg. Soundwaves In a Transverse wave the particle displacement is perpendicular to the direction of wave propagation. Eg. Lightwaves So ordinary Light is a Transverse wave.The particles of the medium vibrates perpendicular to the direction of propagation of waves. When this ordinary light is passed through Polarizer ,the perpendicular vibrations are filtered and hence intensity of light is reduced. Eg: The Windows of the Aeroplane.

Answer 3

Common light sources, like the sun, a fluorescent lamp or a candle flame, are not emitting polarized light. But when light from these sources shines on a polarizing filter, the transmitted light is polarized. For example, sunlight shining on a filter,such as that used in Polaroid sunglasses, becomes polarized light when transmitted.

Answer 4

because polarized light have one wavelength for example monochromatic light, while ordnary light have more than 2 wavelength for example white light

Answer 5

unpolarized light = light waves vibrate in more than one plane

Polarized light = vibrations of light waves occur in a single plane.

Answer 6

Polarized light waves have all of their electric fields oriented in the same direction. Ordinary light waves may have multiple orientations (randomly distributed).

Answer 7

In polarized light, all the photons oscillate in the same direction.

Answer 8

Nothing. :)
