Resonance
- If we look at all physical matters as vibrating energy, we can appreciate that different objects vibrate at different frequencies,
with some resonating on the same frequency.
- If you strike the note C on a tuning fork, for example, every C on an adjacent piano will
vibrate - all the notes on the piano that recognize that note will resonate with the tuning fork.
