Physics
Two sounds of the same loudness and same pitch produced by two different instruments differ in their
- amplitudes
- frequencies
- wave forms
- all the above
Answer
waveforms
Reason — The difference between the two sounds lies in their waveforms, which are determined by the characteristics of the instrument producing the sound hence each instrument produces a unique waveform due to its specific construction and the way it generates sound waves.
