While traveling in the same medium, sound A has a wavelength of 5 meters, while sound B has a wavelength of 10 meters. Which sound will have a higher pitch?(1 point)

Question

Responses

sound B, because it has a higher frequency.
sound B, because it has a higher frequency.

sound A, because it has a lower frequency
sound A, because it has a lower frequency

sound B, because it has a lower frequency
sound B, because it has a lower frequency

sound A, because it has a higher frequency

Answer 1

The correct response is:

sound A, because it has a higher frequency.

To explain: The frequency of a sound wave is inversely related to its wavelength. The formula connecting speed (v), frequency (f), and wavelength (λ) is:

\[ v = f \cdot \lambda \]

Since both sounds are traveling in the same medium, they have the same speed. Therefore, a shorter wavelength (like sound A's 5 meters) corresponds to a higher frequency, while a longer wavelength (like sound B's 10 meters) corresponds to a lower frequency. Higher frequency sound waves are perceived as having a higher pitch.
