How is the speed of sound measured?
The speed of sound is measured by timing how long it takes for a sound wave to travel a known distance. By dividing the distance by the time taken, the speed of sound can be calculated.
What are some examples that demonstrate that sound takes time to travel?
Hearing thunder after seeing lightning because sound travels slower than light. Delay between seeing a distant firework explode and hearing the sound it makes. Hearing an echo in a large empty room due to sound waves taking time to bounce off surfaces and return to the listener.
How long do sounds take to travel?
To travel where? - That would depend on the distance you want it to travel. In air, sound moves at about 310 meters per second (depends on the temperature). This is about 1,236 kilometers per hour (or 768 mph).
How much time does it take to the sound to travel?
Sound travels at a speed of about 343 meters per second, or 1,236 kilometers per hour. It takes sound roughly 3 seconds to travel 1 kilometer.
How far does light travel in the time it takes sound to travel 1 cm in air at 20 C?
Based on the speed of sound being 340 m/s and that of light being 299,792,458 m/s. we get the speed of light being ~881,742 times that of sound. So if sound goes 1cm then light will travel 881,742 cm or 8,817.42 m.
How long does it takes sound to travel 100mm?
0.000292 second
What is an example that demonstrates that sound takes time to travel?
Fire crackers or thunder and lighting.
Why does sound travel slowest thru gases?
Gases have the least amount of molecules and they are spread farther apart so it takes a longer time for the sound energy to travel from molecule to molecule.

How time taken to the nearest second for sound to travel 1km?
It takes 3 seconds.
What is the second report sometimes heard when a rifle is heard from a distance?
The FIRST sound would be the crack of the bullet making a sonic boom- most travel faster than the spped of sound. The second is the sound of the gun firing- it takes longer for the sound to get to you than the bullet takes to get to you.

How long does it take for sound to travel 30 meters away?
Sound travels at approximately 343 meters per second in air at room temperature. To calculate the time it takes for sound to travel 30 meters, you can use the formula: time = distance/speed. Thus, it would take about 0.087 seconds for sound to travel 30 meters.
How much time does it take to the sound to travel?
Sound travels at a speed of about 343 meters per second, or 1,236 kilometers per hour. It takes sound roughly 3 seconds to travel 1 kilometer.
Simple experiment to compare steel and cast iron?
A steel specimen would give a longer or continuous sound when beaten by a hammer. This is due to the malleable nature of the material. In other words, sound takes longer to travel in a coarse-grained material. Whereas cast iron specimen gives sound of shorter duration. This is due to the brittle nature of the material. In other words, sound takes shorter to travel in a fine-grained material.
How long does it takes a sound to travel a distance of 1900 feet?
In dry air at sea level and atmospheric pressure, 1.69 seconds.
