Does anyone know what frequency the open E string vibrates at?

Also, if anyone knows;

4th string tuned down to C#?

5th string tuned to B?

5th string tuned to A?

Thanks.

Here's the equation:

(unknown frequency) = (any lower known frequency)*2^(x/12), where x is the number of half-steps that your unknown frequency is above your known. Got it?

For example:

Low E is 41 htz. You want to know what low G# is. G# is 4 half steps above E. Now you apply the math.

(Known frequency) times 2 to the power of (half steps above) divided by 12.

41 Htz times 2 to the 4/12 (or 1/3) power = 41 times 1.230.

We get about 50.4 Htz. Also remember that to create an octave higher, simply double the frequency. To create a lower octave, simply halve it.
