Questions & Step-by-Step Solutions
In which medium does sound travel fastest?
Correct Answer: Solid
Step 1: Understand that sound is a type of wave that travels through different materials.
Step 2: Identify the three main types of materials: solids, liquids, and gases.
Step 3: Know that in solids, molecules are closely packed together.
Step 4: Realize that closely packed molecules allow sound waves to transfer energy quickly.
Step 5: Compare this with liquids and gases, where molecules are farther apart, making sound travel slower.
Step 6: Conclude that sound travels fastest in solids, especially in materials like steel.
Medium of Sound Propagation – Sound travels through different media (solids, liquids, gases) at varying speeds due to the density and arrangement of molecules.
Molecular Arrangement – In solids, molecules are closely packed, allowing sound waves to transfer energy more efficiently compared to liquids and gases.
