On Earth, the speed of sound at sea level — assuming an air temperature of 59 degrees Fahrenheit (15 degrees Celsius) — is 761.2 mph (1,225 km/h). Because gas molecules move more slowly at colder temperatures, that slows the speed of sound; sound moves faster through warmer air.May 31, 2013
What is the exact speed of sound?
What is the accurate speed of sound?
If we consider the atmosphere on a standard day at sea level static conditions, the speed of sound is about 761 mph, or 1100 feet/second. We can use this knowledge to approximately determine how far away a lightning strike has occurred.
How do you calculate the speed of sound?
Assuming the speed of sound in air is 345 m/s, determine the wavelength of the sound corresponding to the note of middle C. Let λ = wavelength. Use v = f • λ where v = 345 m/s and f = 256 Hz. Rearrange the equation to the form of λ = v / f….The Speed of Sound.
| a. one-ninth | b. one-third |

| c. the same as | d. three times larger than |
How fast is speed or sound?
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.
How fast is the speed of dark?
speed of light Darkness travels at the speed of light. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light. Any time you block out most of the light – for instance, by cupping your hands together – you get darkness.
How much faster is light than sound?
The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour. Visible light can also travel through other things besides through air and through space.
What is the speed of sound at 22 degrees Celsius?
The speed of sound in dry air at 22 °C is 344.632 m/s.
What is the speed of sound at 10 degrees Celsius?
337.4
| Temperature – t – (oC) | Speed of Sound – c – (m/s) |

| 0 | 331.4 |
| 5 | 334.4 |
| 10 | 337.4 |
| 15 | 340.4 |
Is anything faster than light?
No. The universal speed limit, which we commonly call the speed of light, is fundamental to the way the universe works. … Therefore, this tells us that nothing can ever go faster than the speed of light, for the simple reason that space and time do not actually exist beyond this point.
