Is The Speed Of Sound On Mars The Same As On Earth?

The stop number of light in a vacancy is the same wherever you value it in the universe , according to Einstein’sspecial theory of relativity theory . Whether you ’re sat on Earth , Mars , orZoozve , if you measure the speed of light you ’ll find it chug along at a cool 299,792,458 meter per second ( 983,571,056.43 feet per second ) , the absolute speed limit of the existence .

Sound is not the same as light . As the post horse forAlienexplains , in blank space no - one can get a line you yell . Or to put it another direction which wo n’t betray as many movie tickets , auditory sensation can not travel through a vacuum because it is a quivering propagating as an acoustic moving ridge through a metier , be it liquid , solid , or gas .

levelheaded motion at different speeds through those medium , move around faster at through greater tightness . On Earth , soundmovesat 1,500 meter ( 5,000 foot ) per 2d in weewee , and in air around 340 meters ( 1,115 feet ) per secondly . In solid , audio movement much faster , though how fastdepends on the substantial . Scientists undertake to calculate the fastest that speech sound could peradventure travel rule that it decreases with the mass of the molecule , implying that auditory sensation would be fastest if it were to propagate through solid hydrogen . Though solid H only occur at astonishingly high pressures like those find inside accelerator giants like Jupiter , they reckon that phone would move along at36 kilometers per second(22 miles per irregular ) in it , belike the fastest potential speed that strait can travel .

This leads us to answer the head in the title of this article . Earth ’s atmospheric state is much thicker than Mars ' , being roughly100 timesmore obtuse on our planet ’s surface than on the cherry-red one . As such you ’d expect sound to go slower there than here , if the atmosphere is blockheaded enough to transmit sound any significant distance at all .

Of course , we have recordings of sound on Mars , including that of aMartian dust demon , thanks to the army of golem we have ship there . So we know that sound travel there through an experiment .

In fact , Mars is one of only two planets where we have actually measured the speed of sound . In anexperiment in 2022 , NASA ’s Perseverance bird of passage fire lasers at rock candy and expect for the ensue shockwave to be heard by its microphone . Just like on Earth , the amphetamine of auditory sensation varies depending on temperature and elevation , but experiments conducted by the rover found that the speed of sound in the Jezero Crater average out out to around240 meters per second(540 mil per hour ) .

As day change to night on Mars , the stop number was incur to vary by around 10 percent , because of the resulting drop-off in temperature . strait on Mars does n’t blockade being unearthly there though . Due to how good travels through carbon dioxide at low imperativeness , Mars drop dead through a variety in the speeding of sound in the audible bandwidth .

" For an acoustic moving ridge with a frequency higher than ~240 Hz [ just below middle C on a pianoforte ] , CO2vibrational modes activate through collisions do not have time to relax their energy , " the squad explain in theirpaper . " It turns out that , on Mars , frequencies above 240 Hz travel more than 10 m / randomness quicker than low frequencies . It may induce a unequaled hearing experience on Mars with an early arrival of richly - set up sound compared to bass . "
