Glass Wave was created in 2008.
The sound wave must match the glass's natural resonating frequency, which means the frequency that it vibrates naturally at, when the glass picks this up, it vibrates with it due to resonance. The glass can vibrate so violently that it shatters.
When a light wave passes from air into glass, it bends towards the normal due to an increase in the refractive index of glass compared to air. This bending of the light wave is known as refraction, and it causes the light wave to change direction as it enters the glass medium.
When a light wave goes through a pane of glass in a window, the light wave slows down due to the change in medium from air to glass and is refracted. Some of the light may also be reflected off the surface of the glass.
