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 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 pitch of a sound is directly related to its frequency: higher frequencies correspond to higher pitches. The frequency of a sound wave can be calculated using the formula:

\[ f = \frac{v}{\lambda} \]

where:
- \( f \) is the frequency,
- \( v \) is the speed of sound in the medium (which is the same for both sounds),
- \( \lambda \) is the wavelength.

Given:
- For sound A, the wavelength (\( \lambda_A \)) is 5 meters.
- For sound B, the wavelength (\( \lambda_B \)) is 10 meters.

Since sound A has a shorter wavelength than sound B, it will have a higher frequency:

- The frequency of sound A will be higher than that of sound B.

Thus, sound A will have a higher pitch.

So the correct response is:

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