Introduction This problem involves harmonics in open and closed cylindrical organ pipes of equal length. We are given a relation between harmonics and are required to find the fundamental frequency of the closed pipe. Understanding the Harmonics In an open organ pipe, all harmonics are present: f₁, 2f₁, 3f₁, … In a closed organ pipe,
Introduction This question involves calculating the wave velocity and tension in a stretched string vibrating in its fundamental mode. We are given frequency, length, and mass of the string, and are asked to calculate the wave speed and tension. Given Mass (m) = 20 g = 0.020 kg Length (L) = 40 cm = 0.40
Introduction We are given the wave function of a transverse wave traveling along a string. The wave equation is: y(x, t) = 0.021 sin(30t − x) We are also given: Linear mass density (μ) = 1.3 × 10⁻⁴ kg/m The goal is to determine the tension (T) in the string. Step 1: Identify Wave Parameters
