What type of sound wave has a higher pitch?

• A. A wave with a longer wavelength
• B. A wave with a lower frequency
• C. A wave with a shorter wavelength
• D. A wave with a high amplitude

Answer: (C)

A wave with a shorter wavelength corresponds to a higher frequency, and frequency is directly related to the perception of pitch in sound waves. The pitch of a sound is determined by the frequency of the wave; a higher frequency means that the wave oscillates more times per second, which is heard as a higher pitch. In contrast, longer wavelengths are associated with lower frequencies, which produce lower pitches. Amplitude relates to the loudness of the sound rather than its pitch, meaning that while a sound with a high amplitude may be louder, it doesn't affect the perceived pitch of the sound. Thus, the wave with a shorter wavelength is indeed the correct choice, as it directly leads to a higher frequency and subsequently a higher pitch.
