Question 488: Waves

Question

A string is cut into three parts, having fundamental frequencies n
1
, n
2
, n
3
respectively.  Then original fundamental frequency n related by the expression as

Accepted Answer

As $$n \propto \left( {1/l} ight)$$
$$l = {l_1} + {l_2} + {l_3}$$
$$ 	herefore {1 \over n} = {1 \over {{n_1}}} + {1 \over {{n_2}}} + {1 \over {{n_3}}}$$

Answer

$${1 \over n} = {1 \over {{n_1}}} + {1 \over {{n_2}}} + {1 \over {{n_3}}}$$

Answer

$$n = {n_1} 	imes {n_2} 	imes {n_3}$$

Answer

n $$=$$ n
1
+ n
2
+ n
3

Answer

$$n = {{{n_1} + {n_2} + {n_3}} \over 3}$$
