Bheke isivinini ifomula yokukhanya. Amanani kanye nomqondo

Kusukela ezinsukwini esikoleni, siyazi ukuthi ijubane lokukhanya, ngokomthetho ka-Einstein ye - kuyinto isiqongo zingenakunqobeka endaweni yonke. Ibanga ukusuka elangeni ukuze umhlaba ukukhanya sihamba kumaminithi 8, nokuthi emhlabeni kwezigidi ezingu-150 km. Ukuze Neptune iza amahora kuphela ngemva kuka 6, kodwa mkhathi kuthatha amashumi eminyaka ukuba unqobe amabanga anjalo. Kodwa akubona bonke abantu uyazi ukuthi ukubaluleka isivinini lingashintsha kakhulu kuye ngokuthi imvelo lapho ukukhanya sihamba.

ijubane Formula ukukhanya

Ukwazi ijubane lokukhanya e vacuo (c ≈ 3 × 10 ⁸ m \ c), omunye kungacacisa ukuthi kweminye abezindaba, esekelwe Inkomba yabo of kwalungiswa izinkunga zokubona n. Ifomula we velocity yokukhanya sifana imithetho mechanical physics, kodwa kunalokho, ekutholweni ibanga usebenzisa isikhathi nesivinini into.

Ngokwesibonelo, sithatha ingilazi Inkomba kabani yezokubona 1.5. Ngokusho ijubane ifomula yokukhanya v = c \ n uthole ukuthi isivinini konemimoya enikeziwe cishe elilingana 200,000 km \ s. Uma uthatha uketshezi, njengamanzi, the velocity esiphelweni ka izinhlayiyana eziningi zokukhanya (izinhlayiya yokukhanya), kuba 226 000 km \ s nge Inkomba yezokubona ka 1.33.

Ifomula we velocity yokukhanya emoyeni

Air - lena futhi ngoLwesithathu. Ngenxa yalokho, it has a okuthiwa ukuminyana optical. Uma izinhlayiyana eziningi zokukhanya esikhaleni nje musa uhlangabezana nezingqinamba endleleni yayo, imvelo, bachitha isikhathi esithile phezu excitation izinhlayiya zama-athomu. I luthe ukuqina medium, isikhathi xaxa esichithwa lena injabulo kakhulu. Inkomba yezokubona (n) emoyeni ilingana 1,000292. Futhi lokho asibahambeli ngempela kude kumkhawulo 299.792.458 m / s.

ososayensi American ephethwe ukubambezela ijubane lokukhanya cishe zero okugcwele. Bangaphezu kuka-1/299 792 458 imizuzwana. Ijubane lokukhanya ngeke bakwazi ukumelana. Into wukuthi ukukhanya - lena wave efanayo kagesi, kanye-X ray, omsakazo noma ukushisa. Umahluko owokuthi umehluko phakathi nombono kanye nobuningi.

Kuvele iqiniso elithakazelisayo ukungabi kunobukhulu bendawo ikhasi lesikhwama sasekhaya, futhi lokhu kubonisa ukuntula isikhathi nezinhlayiya inikezwe. Ngamafuphi nje, i-albhamu yezithombe, owazalelwa eziyizigidi ezimbalwa noma ngisho izinkulungwane zezigidi zeminyaka edlule, esingaphansi yesibili yesikhathi.
