Intro to Progressive Waves | A-level Physics

This video is an introduction to progressive (travelling) waves. We motivate the study of waves by discussing gravitational waves (one of Albert Einstein's predictions) and showing an animation of a neutron star merger. Such waves transfer energy, and we discuss how this is a defining trait of all progressive waves, with the help of a PhET simulation. https://www.youtube.com/@ForestLearn?sub_confirmation=1 We are grateful to NASA/Goddard Space Flight Center for the animation and picture used in the video: https://svs.gsfc.nasa.gov/10543 We are grateful to PhET for the simulation used in the video: PhET Interactive Simulations University of Colorado Boulder http://phet.colorado.edu/ The simulation used is: https://phet.colorado.edu/en/simulations/wave-on-a-string
