The true statement for sound waves is at 0 °C their speed is 332 meters per second. Sound waves cannot be polarized because they are longitudinal waves, and they cannot travel in a vacuum as they require a medium to ...
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 ...
Sound waves travel fastest in solids due to the dense molecular structure that allows efficient transmission of vibrations. In liquids, sound travels slower than in solids, and it is slowest in gases due to their sparse molecular arrangement. Sound cannot ...
The speed of sound in air at room temperature (20°C) is approximately 343 meters per second. Among the given options, the closest approximation is 330 meters per second. This speed can vary slightly with changes in temperature and atmospheric conditions.
The reason thunder is heard long after the flash of lightning is the speed of light is much greater than the speed of sound. Light travels at approximately 300,000,000 meters per second, while sound travels at about 343 meters per ...
