A guitar string is

90 \mathrm{~cm}

long and has a fundamental frequency of

124 \mathrm{~Hz}

. Where should it be pressed to produce a fundamental frequency of

186 \mathrm{~Hz}

View answer and explanation

Correct option: A

0.6

Option A (0.6) is correct because the frequency is inversely proportional to the length of the string, so the new length can be calculated using the ratio of the frequencies.
