Answer / thiru
in fiber optic communication we use a optical source for
generating optical energy like light for
communication.similar way we consider the sunlight has
optical energy and vacuum has a fiber core.now the light
travel in a vaccum and gets all properties of the em wave.

Answer / bob
It seems odd that light can move in a vacuum (propagate).
This was a big question before Einstein's theory of
relativity. It was thought that space was composed of
"aether," a substance that essentially allows light to
travel through it. If this were true, though, the travel of
the earth through space would change the speed of light
depending on which direction you beamed a light source. This
was proven incorrect through the Michelson-Morley experiment
which showed that even though the earth is speeding through
this 'aether,' its speed never changes. Somehow the
electromagnetic wave that is light propagates itself. It
does not need a medium to carry it, so to speak. Thus a
light beam needs no medium in which to travel.

Answer / vens
light does not produces s em wave in vacuum.because em wave
consist of electrical and magnetic waves.so light does does
not contain these component and instead of producing em
wave it takes all properties of em wave like
dispersion,scattering,attunation etc,,,,,,
