Resonant Pendulum
共振擺錘
HK$306.00
The scientific phenomenon behind the transfer of energy is known as "Resonance". If the pendulum is pulled to one extreme and released without pushing, it makes a certain number of oscillations in a unit time. This number is a constant for a given pendulum and is known as its natural frequency or resonant frequency.
能量轉移背後的科學現象稱為「共振」。 如果將擺錘拉到一個極端並在沒有推動的情況下釋放，則它會在單位時間內產生一定次數的振盪。 對於給定的擺，該數字是一個常數，稱為其固有頻率或共振頻率。.
