Light is also nothing but Electromagnetic waves, a section in Electromagnetic spectrum. We get light from the outermost parts of Space; from areas as distant a part, that light yakes 13,000,000,000 year to cover the distance before reaching Earth.
Remember light has a speed of
300,000 km/s (= 1,080,000,000 km/hour).
This is possible, because there is nothing in between (not even air; only void or 'vacuum').
the explanation why you do no longer pay attention any sound is as a results of the fact there at the instant are not any debris in a vacuum to oscillate whilst a valid wave is propagated. The oscillation of debris is the sound wave. Electromagnetic waves are self propagation and have a magnetic and electric field ninety stages to a minimum of one yet another which initiatives it forward. consequently it is not appropriate is the wave is in a vacuum or no longer.. EM waves are radiation .. Its mild that contains photons.. and photons do no longer carry mass, photons are packets of potential.

is a vacuum. The visible light and infrared radiation from the Sun travels through this near vacuum.
yes, they can & it seems you know that.
whats the q?
