Question

the speed of sound waves through two different media, steel and air, was recorded. according to the graph, which of the following statements is true?
sound waves can travel through steel, but not through air
sound waves travel faster through steel than through air
sound waves travel through steel and air at similar speeds
sound waves travel faster through air than through steel

Explanation:

In the bar graph (presumed from the context), the bar for steel is taller than that for air, indicating higher speed for sound in steel. Sound waves do travel through both (so A is wrong), speeds differ (so C is wrong), and steel’s speed is higher (so D is wrong), making B correct.

Answer:

B. Sound waves travel faster through steel than through air
