# How Many Feet Can Sound Travel Per Second

## How far does sound travel in 2 seconds?

API quota exceeded. You can make 500 requests per day.

## How far can sound travel in 3 seconds?

So sound travels 1 kilometer in roughly 3 seconds and 1 mile in roughly 5 seconds.

## How fast does sound travel per foot?

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.

## How far is sound in 15 seconds?

If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you’ll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close.

## Does sound travel 1 mile a second?

In air at a temperature of 70° F (22.2° C), sound travels at a speed of about 1,129 feet (344 meters) per second, which is roughly equivalent to one-fifth of a mile in one second, or one mile in five seconds (or one kilometer in about three seconds).

## How far does light travel per second?

The speed of light traveling through a vacuum is exactly 299,792,458 meters (983,571,056 feet) per second. That’s about 186,282 miles per second — a universal constant known in equations as “c,” or light speed.

## What is the sound of thunder?

At large distances from the center, the shock wave (thunder) can be many miles across. The shock wave is greatly elongated. To the listener, it is the combination of the millions of shock waves that gives thunder the continuous booming/rumbling sound we hear.

## How fast is Lightspeed?

Light from a stationary source travels at 300,000 km/sec (186,000 miles/sec).

## How fast is the speed of dark?

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.

## How fast is sound compared to light?

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. Light will travel through a vacuum at 300 million meters per second.
