The following six (6) items consists of two statements, Statements I a...
Statement I: The pitch of the sound wave depends upon its frequency.
Statement II: The loudness of the sound wave depends upon its amplitude.
Explanation:
Statement I: The pitch of a sound refers to how high or low the sound is perceived by the human ear. It is directly related to the frequency of the sound wave. Frequency is defined as the number of complete oscillations or cycles of a wave that occur in one second. The unit of frequency is hertz (Hz). Higher frequency sound waves have a higher pitch, while lower frequency sound waves have a lower pitch. Therefore, Statement I is true.
Statement II: The loudness of a sound refers to its intensity or amplitude. Amplitude is the maximum displacement of particles in a medium from their mean position when a wave passes through it. It determines the energy carried by the sound wave. The greater the amplitude, the louder the sound. However, it is important to note that loudness is not solely dependent on amplitude. Factors such as distance from the source, medium through which the sound travels, and individual hearing abilities also play a role in determining the perceived loudness of a sound. Therefore, Statement II is true.
Explanation of the relationship between the two statements:
The relationship between the two statements is that the pitch and loudness of a sound wave are two different characteristics that depend on different properties of the wave. While the pitch is determined by the frequency of the sound wave, the loudness is determined by the amplitude of the sound wave. Therefore, both statements are individually true, but Statement II is not the correct explanation of Statement I.
Conclusion:
Both Statement I and Statement II are individually true, but Statement II is not the correct explanation of Statement I.
