When a light is polarized,what happens to its magnetic field?
Also what is light.How it is produced?
Also what is light.How it is produced?
When unpolarized light goes through a polarizing filter, half of the lights energy is absorbed by the filter (that's the idealized short story). The outcoming light's electric field "oscillates" along one transverse axis. The light's magnetic field still oscillates along along an axis perpedicular to the electric field.kiru said:When a light is polarized,what happens to its magnetic field?

Claude Bile said:Light is an electromagnetic wave, which is a disturbance in an electromagnetic field that propagates at a fixed speed.
Most of the light we observe is due to black body radiation, fluroescence can be put down to spontaneous emission, whereas lasers generate light via stimulated emission.

I think Oscillating dipole can also produce light.Isn't it?What I wanted is 'Is light a continuous/discontinuous flow of quanta?'
