## anonymous 4 years ago 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?

1. anonymous

2. anonymous

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

3. anonymous

f=sqrt T?

4. anonymous

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

5. anonymous

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

6. anonymous

Is that all that youre given?

7. anonymous

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

8. anonymous

my f2 is 277?

9. anonymous

yep

10. anonymous

so find the freq. of the loosened string.

11. anonymous

the beat frequency is the difference between the two.

12. anonymous

ok?

13. anonymous

thanks alot sweet heart

no problem, sugar.
