a) a short wavelength and a low amplitude
A high-pitched sound corresponds to a wave with a higher frequency, which means that the peaks of the wave are closer together, indicating a short wavelength. Pitch is determined by the frequency of the sound wave: higher frequency results in a higher pitch, and vice versa. A quiet sound corresponds to a wave with low energy, which is indicated by a low amplitude. Amplitude is related to the volume or loudness of a sound: a larger amplitude results in a louder sound, and a smaller amplitude results in a quieter sound.
