When Vibrations Become Sound

〰️ What happens when we halve a wavelength? The number of vibrations doubles! At the same speed, «length» and «frequency» move in opposite directions. Watch the curve become more tightly packed before your eyes. 🔊 When you hear the wave, frequency becomes «pitch» and amplitude becomes «volume». Yet some sounds with the same pitch and volume still sound different. Find out why a piano and violin play the same note differently—listen for yourself. 🏃 Finally, discover what carries sound. Ring a bell in a vacuum and you hear nothing. Sound travels fourteen times faster through steel than through air—that’s why a train can be heard sooner with your ear on the rail.
