Question

how does the cone work? sound makes sound waves in the air. when sound waves travel through the air in all directions, the waves become weaker. the sound cone captures, or traps, sound waves. it keeps them from spreading out. the cone channels the sound waves into a smaller area, increasing the volume and making a louder sound. which idea from the passage does the diagram on page 4 best support? a sound cone should be placed very close to the ear. sound waves create a louder sound at the small end of the cone. a sound cone should be made using poster board. sound waves become weak when they travel through a cone.

Explanation:

The passage explains that the sound cone captures sound waves and as the sound waves spread out, they become weaker. Making the volume larger at the small - end of the cone can create a louder sound, which aligns with the idea that sound waves create a louder sound at the small end of the cone.

Answer:

Sound waves create a louder sound at the small end of the cone.
