One of the nine jewels of Emperor Akbar, widely known as
Tansen (the king of Music) , was able to break glass by singing
appropriate note. What physical phenomenon could account for this?
Ans: The physical phenomena involved in this trick
is resonance. When the natural frequency of the glass coincides with the
frequency of the singer’s voice, resonance occurs and when amplitude of
the vibration becomes more than the breaking force, the glass cracks.
