In which of the following media is the transmission of sound wave fastest?
Answer Details
The speed of sound waves depends on the medium through which they travel. In general, sound waves travel fastest through solid materials, slower through liquids, and slowest through gases.
Vacuum is a space devoid of any matter, so sound cannot travel through it. Therefore, the option of vacuum is eliminated.
Air is a gas and sound waves can travel through it. However, since the molecules in gases are further apart compared to liquids and solids, sound waves travel slower through air than through solids and liquids.
Wood and Iron are both solid materials, and sound waves can travel through them easily. However, sound waves travel faster through denser materials like iron, which has a higher speed of sound than wood.
Therefore, the answer is Iron. Sound waves travel fastest through iron among the given options.
