7. The D string on a guitar oscillates with a fundamental frequency of 146.8 Hz. Its length is 0.640 m, and in its fundamental mode this length is one half-wavelength. (a) What is the speed of waves traveling along this string? (b) if the linear mass density of this guitar string is 2.3 × 10−3 kg/m, what is the tension in the string? (c) The string sends out sound waves of the same frequency through the air, traveling at a speed of 345 m/s. What is the wavelength of these sound waves?
