Question

The characteristic which determines the Energy carried by sound waves is-

• A. Loudness
• B. Pitch
• C. Quality
• D. None of these.

Answer 1

The correct option is A

Loudness

1. Sound waves travel in the form of energy.
2. Where, Energy in the form of waves, travels from one point to another, with the help of vibrating particles.

An explanation for the Correct answer-

• Amplitude- This term is related to the loudness of a sound, the energy carried by the wave depends upon loudness as well as the amplitude.

An explanation for the wrong answer-

1. Frequency- The frequency of the sound does not carry the energy, It is fixed and since the frequency is dependent upon the pitch, it is also fixed for the wave in terms of energy.
2. Quality of sound depends only on the waveform so it has nothing to do with the energy carried by the wave.

Hence, the correct option is (A) Loudness
