I am not sure how the speed of light is measured, but that of sound is fairly straightforward.
You could set a loudspeaker to emit sound pulses at a microphone connected to a signal-analyser at an accurately-measured distance away, and time the arrival electronically. If the receiving signal-analyser is triggered by the transmitting pulse that drives the speaker, then the delay between trigger pulse and received pulse can be used to calculate the sound speed very accurately.
I think you could use a somewhat similar method for light, but as the speed of electricity is that of light, I'm not sure how to go about it. Possibly send the light around a series of mirrors or a reel of optical-fibre of known length so each pulse arrives "the long way round" after the directly-connected trigger pulse.
What else can I help you with?
Does a megaphone measure light and speed?
No, a megaphone is a device used to amplify sound, particularly human speech. It does not measure light or speed.
Why it harder to measure the the speed of light than it is to measure the speed of sund?
Roughly speaking, light moves about a million times faster than sound in air.
How fast is the speed of sound and speed of light added together?
The speed of sound in air is about 343 m/s, and the speed of light in a vacuum is about 299,792 km/s. When added together, the speed of sound and the speed of light do not directly add up because sound requires a medium to travel through, while light can travel in a vacuum.
Is the speed of sound as speed of light?
The speed of light is much greater than the speed of sound.
How is the speed of light and speed of sound related?
The speed of light is about 900,000 times as fast as the speed of sound in air.
Which was the fastest the speed of light or the speed of sound?
speed of light
Who try to measure the speed of light?
Roemer was the first to measure the speed of light.
What is farster the speed of light or the speed of sound?
The speed of light is more than 850 thousand times the speed of sound.
Why speed of light is greater than speed of sound?
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.
When was The Sound the Speed the Light created?
The Sound the Speed the Light was created on 2009-10-06.
Which is faster the speed of sound in air or the speed of light in air?
Speed of light in air ~ speed of light in vavuum = 3,00 *10^8 m/s speed of sound in air ~ 330 m/s. Speed of light is faster than sound in air
Is the speed of light or sound faster?
The speed of light is about 880 thousand timesfaster than the speed of sound.
