## krypton Group Title Two violin strings are tuned to the same frequency, 277 Hz. The tension in one string is then decreased by 1.92 percent. What will be the beat frequency heard when the two strings are played together? 2 years ago 2 years ago

2. Algebraic!

ok, what expression are you using for frequency as a function of tension?

3. krypton

f=sqrt T?

4. Algebraic!

pretty much, all else being constant and for the purpose of the problem so:

5. Algebraic!

$\frac{ f _{1} }{f _{2}} = \frac{ \sqrt{.9808T} }{ \sqrt{T}}$

Is that all that youre given?

7. Algebraic!

${ f _{1} } = \sqrt{.9808} {f _{2}}$

8. krypton

my f2 is 277?

9. Algebraic!

yep

10. Algebraic!

so find the freq. of the loosened string.

11. Algebraic!

the beat frequency is the difference between the two.

12. Algebraic!

ok?

13. krypton

thanks alot sweet heart

14. Algebraic!

no problem, sugar.
