Part F =6 ANSWER: Answer Requested Normal Modes and Resonance Frequencies Learning Goal: To understand the concept of normal modes of oscillation and to derive some properties of normal modes of waves on a string. A normal mode of a closed system is an oscillation of the system in which all parts oscillate at a single frequency. In general there are an infinite number of such modes‚ each one with a distinctive frequency and associated pattern of oscillation. Consider an example of a system

Physics Waves Lab SL Introduction: This lab will investigate the properties of mechanical waves such as a longitudinal wave‚ focusing on the question: Does a change in the frequency of a wave result in a significant and convincing change in the speed of the wave? Hypothesis: Changing the frequency of the wave will not result in a change in speed because the wavelength will change proportionally as in theory. Student Designed Investigation Procedure/ Planning Procedure: 1. Three
