Nov 1, 2005 · Can sound waves travel faster than the speed of light? Yes, says Joel Mobley, a physicist at the University of Mississippi in the US. In simulations Mobley has shown that ultrasound pulses could move at "superluminal" speeds when they enter water that contains thousands of tiny plastic beads.

That said, light can be slowed down by being passed through transparent materials – by around 33 per cent in the case of glass. Even so, it still zooms through glass around 50,000 times faster than sound waves. Read more:

The first notable difference between the speed of sound and light is how fast they are. In Earth’s atmosphere, the speed of sound averages at about 761-miles per hour (1,225-kilometres per hour). That may seem fast, yet when compared to the speed of light, it seems quite small. Light travels at a staggering 670-million miles per hour (1.07-billion ...
In order for sound to exist, it must have a medium to travel through. For sound, this medium is air, and that’s why sound does not exist in the emptiness of space. Meanwhile, light does not need a medium to exist. Rather, light travels independently of any medium, and thus it can travel through space, unlike sound.
Another notable difference between light and sound is that the speed of light is constantwhile the speed of sound is not. Since the speed of sound requires air to exist, its speed is dependent upon the density and temperature of air. For example, when we say that sound travels at 761-miles per hour, this is only the case at sea level and when tempe...
The speed of sound is fast, yet it is by no means the fastest thing in the universe. It is not even the fastest thing on Earth. Human’s have broken the sound barrier countless times, a speed known as supersonic speed. Light is a different story, however. The speed of light is a fixed law of nature, and it represents the fastest possible speed anyth...
Dec 29, 2006 · The speed of sounds is approx. 300 m/s (1000 ft/s), while the speed of light is 300,000 km/s (approx.190,000 miles/s). Therefore, the sound arrives about 1/3 of a second after the corresponding movement, i.e. starts to be recognizable. In a theater the time difference is too short to be recognized.
Sep 27, 2015 · The speed of sound through air is about 340 meters per second. It’s faster through water and it’s even faster through steel. Light will travel through a vacuum at 300 million meters per second. So they’re totally different scales. No information can propagate faster than the speed of light.
In fact, nothing can travel faster than the speed of light. By comparison, sound travels just 340 m in one second, about the length of three and a half hockey pitches.
Apr 26, 2018 · Light travels faster than sound even in water. If you are asking why sound is slower when it is in air than water, and why light is faster in air than in water, here is why: Light waves are electromagnetic transversal waves.
