Decreasing the amplitude and increasing the wavelength of a sound wave would result in hearing what?
Understand the Problem
The question is asking about the effects of modifying a sound wave's amplitude and wavelength on human perception. Lowering the amplitude typically makes the sound quieter, while increasing the wavelength generally leads to a lower frequency, which could result in a deeper sound. The overall effect on hearing will depend on these changes in properties of the sound wave.
Answer
Softer sound with a lower pitch.
Decreasing the amplitude and increasing the wavelength of a sound wave would result in hearing a softer sound with a lower pitch.
Answer for screen readers
Decreasing the amplitude and increasing the wavelength of a sound wave would result in hearing a softer sound with a lower pitch.
More Information
Amplitude affects the loudness of sound — lower amplitude means a quieter sound. Wavelength affects the pitch with longer wavelengths corresponding to lower frequencies (and thus, lower pitch). Perceived sound might also depend on other factors like context or environmental noise.
Tips
A common mistake is confusing amplitude and wavelength with each other, as well as their effects on sound — amplitude modifies loudness, while wavelength affects pitch.
