They are not. So the question is seriously misguided.
No. Light travels much faster than sound.
They don't really travel at the same speed, but, on television, the distance they travel is so short, that the difference between the speed of sound and the speed of light is almost non-existant.
The speed of light is much greater than the speed of sound.
The speed of sound through air is about 340 meters per second. (The speed of sound in water is about 4 times faster than this). The speed of light in air is about 300 million meters per second.
They never do.
The speed of light is about 900,000 times as fast as the speed of sound in air.
speed of light
The speed of light is more than 850 thousand times the speed of sound.
The speed of light is faster than the speed of sound. Lightning and thunder happen at the same time, but the light reaches your eyes before the sound reaches your ears.
'Radio' waves are physically and electrically identical to light waves except for their frequency (wavelength), and they travel at the same speed as light does.
The speed of light is the speed at which electromagnetic waves propagate through a medium. The speed of sound is the speed at which acoustic waves propagate through a medium. As the speed of sound relies on the medium moreso than the speed of light, sound propagates much slower than light.
