Solution
The correct option is B Pitch - Frequency
Quality - Waveform
Loudness - Amplitude
Pitch refers to the shrillness of the sound. It depends on the frequency. As frequency increases, pitch (i.e. shrillness) also increases.
Loudness refers to the perceived strength of the sound. It depends on intensity, which in turn depends on the amplitude. Loudness increases with amplitude of the sound.
The quality of the sound refers to the characteristics of the sound that distinguishes 2 sounds of same pitch and loudness. It depends on the shape of the waveform of the sound.
