The key characteristics of wave diagrams that relate to air pressure (or sound waves) are amplitude (height of the wave) and frequency (the number of wave cycles that occur in a given time period).
In your description:
- Wave A is described as "taller and skinnier" than Wave B. This implies that Wave A has a higher amplitude (taller) and potentially a higher frequency (skinnier, meaning the waves are closer together in time).
Given this information:
- Wave A having greater pitch and frequency aligns with the idea that higher frequency corresponds to a higher pitch.
Therefore, the best description based on the information is:
Wave A has a greater pitch and frequency.
