Sound waves are longitudinal waves. They consist of compressions and rarefactions that travel through a medium, such as air, water, or solids. Unlike transverse waves, which oscillate perpendicular to the direction of wave propagation, longitudinal waves oscillate parallel to the ...

Supersonic aircraft fly at speeds greater than the speed of sound, known as Mach 1. This speed varies depending on altitude and atmospheric conditions but is approximately 343 meters per second at sea level. These aircraft can travel faster than ...
The velocity of sound in air increases with increasing temperature. This is because warmer air has more energy, causing air molecules to move faster and transmit sound waves more quickly.
The speed of sound is maximum in solids due to their tightly packed molecules, which facilitate faster sound wave transmission. Among the options, iron has the highest density and rigidity, leading to the fastest speed of sound. Therefore, at 20 ...
The velocity of sound varies across different mediums and is highest in solids. This is due to the tightly packed molecules in solids, which facilitate quicker transmission of sound waves. In contrast, sound travels slower in liquids and slowest in ...
