Q126 / 150 · MHT CET 2026 (20 April Shift 1) · Physics
The 'Loudness' and 'Pitch' of sound respectively are the human perception to
- Correct answerAintensity of sound and frequency of sound.
- Bintensity of sound and velocity of sound.
- Cfrequency of sound and velocity of sound.
- Dfrequency of sound and intensity of sound.
Solution
Loudness is the physiological sensation of sound which is directly related to the intensity of the sound wave. A higher intensity sound is perceived as louder.
Pitch is the characteristic of sound that determines its shrillness or flatness, and it is directly related to the frequency of the sound wave. A higher frequency sound is perceived as having a higher pitch.
Therefore, loudness and pitch are the human perceptions of the intensity of sound and the frequency of sound, respectively.
Answer: intensity of sound and frequency of sound.
Pitch is the characteristic of sound that determines its shrillness or flatness, and it is directly related to the frequency of the sound wave. A higher frequency sound is perceived as having a higher pitch.
Therefore, loudness and pitch are the human perceptions of the intensity of sound and the frequency of sound, respectively.
Answer: intensity of sound and frequency of sound.
Hence, the correct answer is option: 'A'.
