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 ...
Sound travels fastest through Steel. Steel has a higher density and elasticity compared to other substances listed, allowing sound waves to propagate faster. This property makes steel an excellent conductor of sound in industrial and structural applications.
If the pressure is doubled, the speed of sound in air remains 332 m/sec. The speed of sound in a medium like air primarily depends on temperature, not pressure. Therefore, changes in pressure do not significantly affect the speed of ...
Bats can fly in the dark because they produce very intense sound waves which control it. Bats use echolocation, emitting high-frequency sound waves and interpreting the echoes to navigate and locate prey in darkness. This biological adaptation allows them to ...
Explosions are not heard on the Moon away from the surface Due to the absence of atmosphere. Sound requires a medium like air to propagate, and the Moon’s vacuum-like environment lacks air molecules necessary to transmit sound waves. Therefore, no ...
Humans feel sound vibrations in the frequency range of 20-20,000 Hz. This range encompasses the audible spectrum where human ears are sensitive to vibrations in the air, allowing us to perceive sound from low-pitched tones to high-pitched sounds like bird ...
