How can we break a glass with sound? 🥽 Every material has a resonant frequency, a specific vibration rate that produces its unique tone, and when sound waves match that frequency, they drive the glass to vibrate in sync and grow in amplitude. As more energy is delivered at that exact pitch, the stress builds until the glass can no longer hold together and shatters, a powerful example of resonance, sound waves, and energy transfer in action. #ScienceExperiment #ScienceFacts #LearnSomethingNew #D
