Question
A string in a musical instrument is 50 cm long and its fundamentlal frequency is 800 Hz. If a frequency of 1000Hz is to be produced, then required length of string is
Options
A.37.5 cm
B.40 cm
C.50 cm
D.62.5 cm
Solution
We know that for frequency of sound in string the formula is,
v =
or v = 
l2 = 50 ×
40 cm
v =
or v = l2 = 50 ×
