What happens when sound travels faster than light?
For the first time, scientists have experimentally demonstrated that sound pulses can travel at velocities faster than the speed of light, c. William Robertson’s team from Middle Tennessee State University also showed that the group velocity of sound waves can become infinite, and even negative.
Is it possible for sound to travel at the speed of light?
Can sound waves travel faster than the speed of light? Yes, says Joel Mobley, a physicist at the University of Mississippi in the US. The phase velocity is the speed at which a wave of a single wavelength moves, and is typically about 1.5 kilometres per second for sound waves in water.
Can you travel faster than the speed of sound?
Yes, wind can travel faster than the speed of sound. The speed of sound is not a fundamental speed like the speed of light is. The speed of sound just describes how fast a mechanical wave travels through a material.
What would happen if sound was as fast as light?
If sound was as fast as light: Every sound wave is a vibration of some particle. Since the speed of sound is the speed of the particle, the particle will be also be moving at light speed. According to Einstein, mass would increase with increasing velocity.
Can particles vibrate at the speed of light?
In practice scenario, particles can’t vibrate in the speed of light. If in anyway sound traveled at the speed of light then the particles carrying sound waves turns into photons and it also turns into electromagnetic wave. And that sound can’t be heard by human ears.
What happens to the mass of particles at the speed of sound?
Since the speed of sound is the speed of the particle, the particle will be also be moving at light speed. According to Einstein, mass would increase with increasing velocity. At the speed of light, mass of the particles will become infinite.
Is it possible to travel at the speed of light?
If you look at the speeds of light and sound in a specific medium, this is actually possible.
