-- Sound is the result of material particles vibrating forward and backward in a
substance, along the direction in which the sound is moving.
-- Light is the result of oscillating electrostatic and magnetic fields, perpendicular
to each other, and perpendicular to the direction in which the light is moving.
-- The speed of sound depends on the mechanicalcharacteristics of the substance
through which it's moving.
-- The speed of light depends on the electricalcharacteristics of the substance or
space through which it's moving.
Now, why would you expect that their speeds might be equal, or even close ?

Why sound travels faster then light in television?
It doesn't. Light travels at a speed of 300,000 km/second; sound travels roughly a million times slower. By the way, the light you see and the sound you hear in television doesn't travel as light or sound for most of the way - the information is encoded in a radio wave (which also travels at the speed of light). Only in the television set is the information transformed back into normal light, and sound.
