When comparing the two waves that are shown, how would Wave A (green wave) differ than Wave B (black wave)?

Wave A and B have the same amplitude, but wave B (black) has a lower pitch.

Wave A and B have the same amplitude, but Wave A has a lower pitch.

Wave A and B have the same pitch, but Wave A is a softer sound.

Wave A and B have the same pitch, but Wave B is a softer sound.

the amplitude of the sound wave

Sound is able to travel faster in solids than in air because the molecules in a solid are
