Question

or low it is. the higher the frequency of a sound wave is, the higher presents a sound wave. put the waves in order from lowest to highest pitc

Explanation:

Pitch depends on sound wave frequency: more waves in the same time frame mean higher frequency and higher pitch. Count the number of full/partial wave cycles for each graph:

1. Top graph: 2 full wave cycles (lowest frequency, lowest pitch)
2. Second graph: 3 full wave cycles
3. Fourth graph: 3 full wave cycles (same frequency as second, but ordered by visual count)
4. Third graph: 4 full wave cycles (highest frequency, highest pitch)

Answer:

1. Top graph (2 wave cycles)
2. Second graph (3 wave cycles)
3. Bottom graph (3 wave cycles)
4. Third graph (4 wave cycles)

Ordered from lowest to highest pitch.
