A spoon can sound like a bell. Explain scientifically in detail.

Answers

So the question is how can a spoon sound like a bell. Sound waves are mechanical waves that have their frequency. When a source, in this case a spoon and a bell oscilate, they produce sound waves. If they produce those sound waves in the same frequency, then we can say they produce the same tone thus they sound the same.
