Dear Prof Scott

The speed of Sound is 340.29 m/s.

1 How the speed of Sound is Computed to get the above value?.

2 Are there many methods to compute the speed of Sound Experimentaly?.

Thanks & regards

1 When the speed of sound is taken at various temperature and various pressures,

a linear equation can be set up to estimate the exact speed of sound at normal pressure and temperature, whatever that may be. I believe it is commonly computed at sea level and 70 degrees, but it doesn't have to be. See the Handbook of Chemistry and Physics for a common reference.

2 The most common method could be a stop watch over a noticable distance between two people.

It could also be computed with a watch and two people with a sizeable distance between them.

Perhaps an item that falls over or changes color could be used with a fair distance between them and only one person observing when this happened. A computer could have two sound detection units with again a noticable difference betwwen them, and this would be the most accurate. Depending what units are used, different results would be found. The farther the distance between the two points, the better the results would be. Ideally, it would be done in an area where there is no wind.

I can answer almost anything that is sent in. If I can't, I'll let you know, but I don't expect that to happen much.

I have known about number theory since the mid 80's. I have answered over 250 questions on Number Theory with this software. Altogether, I have answered over 8,500 questions in mathematics.**Publications**

You're looking at it ... I've answered over 8,500 quesitons in mathematics right here.
**Education/Credentials**

My credentials are an MS in Mathematics at Oregon State in 1986;
I received a BS in Mathematics at the same place in 1984.**Awards and Honors**

I graduated with honors in Mathematics when getting my BS degree and my MS degree.
**Past/Present Clients**

I have assisted many students in mathematics at OSU.
Perhaps I have assisted one of you're friends in math on a computer somewhere else,
but you don't even know... That would be late last night, perhaps with thousands of miles between us ...
Then again, if you're in Washington, so am I ...
