Question

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)
Responses

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

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

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

sound B, because it has a lower frequency

Answer 1

The pitch of a sound is determined by its frequency. The relationship between wavelength (λ), frequency (f), and the speed of sound (v) in the same medium can be described by the equation:

\[ v = f \times λ \]

Given that sound A has a wavelength of 5 meters and sound B has a wavelength of 10 meters, we can deduce their frequencies relative to each other. Since they are traveling in the same medium, their speeds are the same.

- For sound A (λ = 5 m):
- The frequency will be higher because the wavelength is shorter.

- For sound B (λ = 10 m):
- The frequency will be lower because the wavelength is longer.

Therefore, sound A has a higher frequency and, consequently, a higher pitch.

The correct response is:

**sound A, because it has a higher frequency.**
