Introduction
Sound mirrors are a world war era site in the UK and can be modelled by a quadratic. They work in the same way as any satellite dish. Research the ‘focus’ of a parabola, look up the mirrors on google earth (or use another satellite dish) and insert the image into desmos or geogebra. What’s the equation, how does it all fit together?
