It is said that when Tansen sang, the window panes or glass glasses would break into pieces. If this were possible, what property of sound would cause it?

If Tansen’s singing could break window panes or glass glasses, it would be due to resonance (Option C). Resonance occurs when an object is exposed to sound waves that match its natural frequency. In this case, the glass has a specific natural frequency at which it vibrates. When Tansen sang at a pitch that matched this frequency, the sound waves would cause the glass to vibrate at its natural resonant frequency. This would result in the vibrations being amplified significantly. If the amplitude of these vibrations became too great, the structural integrity of the glass could be compromised, leading to it shattering. This phenomenon is a powerful demonstration of resonance, where even small initial vibrations can build up to destructive levels if the driving frequency matches the natural frequency of the material.
