ASVAB General Science - Additional Info Sample Questions

Which of the following is FALSE regarding sound?

Correct Answer:
sound travels faster than light


sound is fundamentally a mechanical vibration that propagates through an elastic medium, such as air, water, or solids, as a longitudinal wave. when an object vibrates, it causes the particles of the medium to oscillate back and forth from their resting positions, creating a wave of compression and rarefaction. this mechanical wave requires a medium to travel through and cannot propagate through a vacuum, unlike electromagnetic waves such as light.

one of the key properties of sound is its speed, which varies depending on the medium through which it travels. typically, sound travels faster in solids than in liquids, and faster in liquids than in gases. this speed variation is due to differences in the densities and elastic properties of the mediums. in air, at standard temperature and pressure, the speed of sound is approximately 343 meters per second (m/s), while in water, it is around 1482 m/s, and in steel, it is about 5100 m/s.

in contrast, light, which is an electromagnetic wave, travels at a speed of approximately 299,792 kilometers per second (km/s) in a vacuum. this fundamental speed, known as the speed of light, is much faster than the speed of sound in any medium. light's ability to travel at this constant speed in vacuum and its independence from a medium for propagation are significant distinctions from sound.

the statement "sound travels faster than light" is, therefore, false. the speed of light far exceeds the speed of sound. this fact is crucial in many phenomena in physics and has been confirmed by numerous experiments. for example, during a thunderstorm, we see lightning before we hear thunder because the light from the lightning (traveling at the speed of light) reaches us much sooner than the sound of the thunder (traveling at the speed of sound).

lastly, the speed of sound is defined as the distance that sound waves can travel in a given amount of time through a particular medium. this velocity can change based on environmental conditions like temperature and pressure, as well as the medium's physical properties. however, under no normal conditions does the speed of sound approach or exceed the speed of light. this discrepancy between the speeds of sound and light is key to understanding various natural and technological processes, from the timing of sonic booms to the synchronization of audio and visual components in broadcasting.
