Answer :
Final answer:
Sound waves travel better through solids than through air due to the efficient transmission of sound in solids through reflection and echoes.
Explanation:
Sound waves can travel through different mediums like air and solids. When it comes to hearing someone from a distance, the friend on the other side of the playground would be better able to hear you through a solid because solids transmit sound waves more efficiently compared to air.
When sound waves hit a solid surface, they reflect and create echoes, allowing the sound to travel further and be heard clearly. This is due to the properties of reflection and how sound waves interact with different materials.
For example, if you shout across a field of grass, the sound waves would disperse and be absorbed by the air, making it harder for your friend to hear compared to shouting against a solid wall where the sound waves reflect and carry the sound better.
