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.

Does sound and light travel at the same speed?
no, light is faster
Does light travels the same way as sound?
No. Light can't travel through solid brick, steel etc, but sound can.
When is the only time sound waves travel the same speed as light?
They never do.
Why do pop and spray not occur at the same time?
Light and sound travel through the air.
Why does a baseball bat crack?
The speed of sound is about 350 m/s (about 400 yards/second). If you are 400 yards away from the batter, then it could take about 1 second for the sound to reach you in the more distant stands. Light takes less than one millionth of a second to travel the same distance. On TV, it depends on how far away the microphone is from the batter as to how noticeable the delay is. They usually have their microphones fairly close to the field and batter so you don't notice the delay as much on TV. Source: wikipedia
Why sound comes first instead of light when you switch on the TV as light travels first?
In the old days, TV Tubes took time to heat up to operate. The new TV's Flat screens may not have the same difference.
Is polarization a property of light waves but not sound waves?
That is correct. Polarization is possible only when the direction of vibration is perpendicular to the direction of the wave travel, such is in light. In sound waves, the direction of vibration (compression) is the same direction as the direction of the travel of the sound wave, and therefore polarization is not possible.
Do radio waves travel at the speed of sound at the speed of light or at some speed in between?
'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.
If light travels at 186000 miles per second in a perfect vacuum at what speed does sound travel under the same conditions?
Sound doesn't travel at all in a perfect vacuum. Sound needs a material substance to move anywhere.
What word has the same vowel sound as light?
Bite has the same vowel sound as light.
Does sound and light need the same medium to travel?
as we know that according to Einstein explanation light travelled very faster then the sound this means that light even can travelled without a medium.bue sounds need travelling vaccum to travelled in
Though sound and light have the same wave equation why doesn't light diverge?
Oh it does ! Try shining a light, even a laser, through a small hole in foil or cardboard. When comparing sound and light, don't forget to allow for the difference in wavelength, and adjust the dimensions of the expected phenomena accordingly. Maybe a better comparison would be between sound and radio ... FM or low-band TV ... since the wavelengths are comparable.
