Igcse Model Questions Vol1 2023 Physics Question 7
Practice objective / multiple choice question 7 from the 2023 Igcse Model Questions Vol1 Physics examination.
A string 1.20 m long is fixed at both ends. Its linear mass density is \(5.0\times10^{-3}\ \text{kg m}^{-1}\). Initially a mass of 0.80 kg hangs from the string, providing the tension. The string vibrates in its fundamental mode. The source frequency is then increased by 20 % while an additional 0.20 kg mass is added to the hanging weight. What is the wavelength (in metres, to two decimal places) of the wave travelling in the string after these changes?
