Wave Propagation & The Human Ear
Found out why you only get Long Wave radio when you’re driving through the hills - it’s to do with the way the lower frequencies can bend around obstacles, while higher frequencies (like FM radio) just bounce off them. Thank god for Atlantic 252!
Finished by looking at how the ear works. Apparently it is a transducer, which converts acoustic energy into kinetic energy and then electrical energy.
Lesson of the day: Never use cotton buds in your ears
