Wave Properties on a String (Includes Prelab Assignment) Objective: Understanding waves and wave motion on a string. We will verify two basic relations for mechanical waves. 1. The product of the frequency and wavelength of the waves is equal to the velocity of the wave. This is written as: v=λfwhere vis the velocity, fis the frequency and λis the wavelength. 2. For the case of waves traveling on a string, the velocity of the wave is related to mass per unit length of the string and the string tension F, as v=Fμ.Apparatus The apparatus includes: 1. Variable frequency mechanical drive 2. Function (waveform) generator with frequency meter 3. String--pulley--hanging mass system including 2 different strings 4. Meter stick 5. Analytical scale (milligram precision) 6. Computer with Data Studiosoftware The Physics:
