Question

if a violin string Is 12inches long and vibrates 440 times per second what is the length shortened to 660 times per second

Answer 1

hint : \( \large f \propto \frac{1}{l}\)

Answer 2

\(f\) : frequency of vibration
\(l\) : length of string

Answer 3

so is it 440x1/12 ?

Answer 4

\(\large \frac{f_1}{f_2} = \frac{l_2}{l_1}\)

\(\large l_1 \times \frac{f_1}{f_2} = l_2\)

Answer 5

\(\large 12 \times \frac{440}{660} = l_2\)

Answer 6

simplify completely

Answer 7

0.061

Answer 8

try again

Answer 9

12*440= 5280 / 600 = 8.8 ?

its **660

Answer 11

you need to divide by 660, not 600
