The speed of sound at 20°C is 343 m/s or 1236.3 km/h all over the world.

In USA they need for the speed of sound at 68 degrees Fahrenheit 1126.713 feet per second or 768.2 miles per hour. Important is the temperature.

Can tornadoes travel faster then the speed of sound?

No, tornadoes cannot travel faster than the speed of sound. The fastest tornado winds ever recorded were around 300 mph, while the speed of sound is approximately 767 mph. Therefore, tornadoes are not capable of exceeding the speed of sound.


How fast does sound travel through steel mph?

Sound travels through steel at approximately 17,600 meters per second, or approximately 39,370 miles per hour.


Do LIGHT WAVES TRAVEL FASTER THAN SOUND WAVES.?

Yes, light waves travel faster than sound waves. Light waves travel at a speed of approximately 186,282 miles per second (299,792 kilometers per second) in a vacuum, while sound waves travel at speeds ranging from around 767 mph (1,225 km/h) in air.


How many ways does sound travel?

Sound can travel through air, liquids like water, and solids like walls and floors. Sound waves can also travel through gases, such as carbon dioxide and helium. In a vacuum, however, such as outer space, sound cannot travel because there are no molecules to carry the sound waves.


How many times faster is the speed of light in a vacuum than the speed of sound air?

100% - sound is vibration of atoms/molecules - it cannot travel through vacuum ___________________________ The idea of "speed pf sound in a vacuum" is meaningless; sound cannot travel without a medium such as air, water, metal, stone, or SOMETHING. Sound waves are mechanical vibrations; there has to be something to vibrate. The speed of sound in air is around 700 miles per hour, while the speed of light is 186,000 miles per SECOND.
