Physics MDCAT / ECAT | Lecture 14 | Production of Stationary Waves | PCTB Insaf Academy

Welcome to this lecture on Production of Stationary Waves by PCTB Insaf Academy, where we will discuss what exactly stationary waves are and how to produce them. We will also look at related MCQ’s from MDCAT/ECAT past papers. Stationary waves are one of the most important wave phenomena in physics, and they can be produced in various systems including strings and air columns. They are a combination of two waves travelling in opposite directions with the same frequency and wavelength, making them appear to be 'standing still'. In a stretched string, stationary waves are produced by plucking or bowing the string, setting up a wave that travels back and forth along the string. In an air column, stationary waves are produced by setting up a vibrating column of air by blowing across a tube or blowing into a whistle. The important parameters for stationary waves are the frequency and wavelength, which can be determined by the length and tension of the string, or the geometry of the air column. These parameters are important for MCQ’s in the MDCAT/ECAT papers, so make sure to understand them thoroughly. We hope this lecture has given you a better understanding of stationary waves and how to produce them. For more information and practice questions, make sure to visit PCTB Insaf Academy. Good luck!
