Gce Model Questions Vol1 2019 Physics Question 26
Practice objective / multiple choice question 26 from the 2019 Gce Model Questions Vol1 Physics examination.
A string \(0.80\) m long is fixed at both ends. When it vibrates in its third harmonic its frequency is \(120\) Hz. The tension in the string is then increased so that the new tension is \(2.25\) times the original tension. Assuming the linear mass density of the string does not change, what is the new frequency of the third harmonic? Give your answer in Hz.
