Shrillness of sound is determined bya)velocity of soundb)amplitude of ...

The correct answer is wavelength of sound.

Confusion Points

It is true that the shrillness of sound is determined by its frequency but frequency and wavelength are inversely proportionate. So, it is also true to say that the shrillness of sound depends on its wavelength.
Since frequency and wavelength are inseparably interlinked (velocity= wavelength x frequency and velocity are constant in a medium).

Key Points

The Shrillness of the sound is determined by the frequency of the vibration.
High-pitched noises can be characterized as having a shrill quality.
We describe a sound as being harsh and having a higher pitch if the vibration frequency is higher.
Low pitch is a description of a sound whose vibration frequency is lower.
Pitch can be thought of as the unit of measurement for sound frequency expressed in Hertz.

The velocity of Sound:

The distance that sound energy will travel through that material in a specific amount of time.
It depends on the material's density, acoustic impedance, and temperature.

The amplitude of Sound:

The height of a sound wave is quantified by its amplitude.
The loudness or the maximum displacement of vibrating medium particles from their mean position at the time the sound is produced.

Wavelength of Sound:

The distance separating two wave crests or troughs that occur consecutively.

Shrillness of sound is determined bya)velocity of soundb)amplitude of ...

Wavelength of sound

- The shrillness of sound is determined by the wavelength of the sound wave.
- Shrill sounds have shorter wavelengths compared to lower-pitched sounds.
- Shorter wavelengths result in higher frequencies, which in turn are perceived as higher-pitched sounds.
- Therefore, a sound with a shorter wavelength will be perceived as more shrill.

Amplitude of sound

- The amplitude of a sound wave is related to its loudness, not its pitch or shrillness.
- Higher amplitudes result in louder sounds, but they do not affect the pitch or shrillness of the sound.
- Therefore, the amplitude of a sound wave does not determine its shrillness.

Velocity of sound

- The velocity of sound in a medium is determined by the properties of the medium, such as temperature and density.
- The velocity of sound does not directly affect the pitch or shrillness of the sound.
- Therefore, the velocity of sound does not determine the shrillness of a sound.

Therefore, the correct answer is option C: Wavelength of sound. The wavelength of a sound wave directly influences its pitch, with shorter wavelengths corresponding to higher pitches and therefore, a more shrill sound.
