A sonometer wire has a length

114 \mathrm{~cm}

between two fixed ends. Where should two bridges be placed, so as to divide the wire into three segments whose fundamental frequencies are in the ratio

1: 3: 4

View answer and explanation

Correct option: A

l_1=72 \mathrm{~cm}, l_2=24 \mathrm{~cm}, l_3=18 \mathrm{~cm}

Option A (

l_1=72 \mathrm{~cm}, l_2=24 \mathrm{~cm}, l_3=18 \mathrm{~cm}

) is correct because the lengths satisfy both the total length condition and the inverse frequency ratio condition.
