WebSee Answer Question: Exercise 4 Suppose that the linear density of the string on a violin is 7.8*10-4 kg/m. A wave on the string has a frequency of 440 Hz and a wavelength of 65 cm. What is the tension in the string? Answer: 63.8N Show transcribed image text Expert Answer Transcribed image text: WebAug 13, 2024 · No headers Recall that speed of a wave on a string is determined by the density and tension; v = ( T / μ) 1 / 2 where T is the tension in the string in Newtons and μ is the mass per length in kilograms per meter). We also know that once the speed is fixed, frequency (in Hertz) and wavelength (in meters) are inversely proportional; v = f λ. matteo bertetto photography
