16PRACTICE PROBLEM
Consider a guitar string made from an elastic material that can support standing waves when stretched between two fixed points. This guitar string is 14 cm long and has a cross-sectional area of 78 mm². The material's density is 980 kg/m³. When the string is under a tension of 400 N, find the lowest frequency of the guitar string.
