Dec 30, 2022 · Light travels at a staggering 670-million miles per hour (1.07-billion kilometres per hour). That’s around 880,000 times faster than the speed of sound. Sound Must Have A Medium
According to Einstein's Special Relativity, the speed of light has a unique status: it's a fundamental feature of our Universe, representing the maximum speed at which information can travel from place to place. As such, nothing can match the 300,000km/s achieved by light travelling through a vacuum – least of all sound, which being waves of ...
The speed of light is significantly faster than the speed of sound. Light travels at a speed of approximately 299,792 kilometers per second in a vacuum, while sound travels at a much slower speed of about 343 meters per second in air.
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.
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.
Sep 27, 2015 · Light doesn’t need a medium to travel. The speed of sound through air is about 340 meters per second. It’s faster through water and it’s even faster through steel.

Can information propagate faster than the speed of light?
Sound only travels at about 330 m/s through the air, so light is nearly a million times faster than sound. If lightning flashes 1 kilometre away from you, the light reaches you in 3 millionths of a second, which is almost instantly.
