Mafunde Owala: Chochitika Chachilengedwe Chomwe Chimaunikira Dziko Lonse
Kuunika ndi chimodzi mwa mitundu yofunika kwambiri ya mphamvu komanso yofunika kwambiri pa moyo padziko lapansi. Popanda kuwala, dziko lapansi likanakhala lamdima komanso lopanda anthu. Mu fizikisi, kuwala kumagawidwa ngati mafunde amagetsi omwe amatha kufalikira kudzera mu vacuum, zomwe zimatilola kuwona dziko lotizungulira momwe timalidziwira lero. Nkhaniyi ikambirana za mafunde a kuwala, makhalidwe awo, momwe amagwirira ntchito, ndi momwe amagwiritsidwira ntchito pa moyo watsiku ndi tsiku.
Makhalidwe Oyambira a Mafunde Owala
Mafunde a kuwala ali ndi mawonekedwe awiri, zomwe zikutanthauza kuti amatha kuchita ngati mafunde ndi tinthu tating'onoting'ono. Kapangidwe kameneka kamadziwika kuti wave-particle duality, komwe kamabwera kudzera mu quantum mechanics. Monga mafunde, kuwala kumakhala ndi mafunde ndi mafupipafupi. Mafunde a kuwala amayambira pa nanometers pafupifupi 400 (pa kuwala kwa violet) mpaka 700 nanometers (pa kuwala kofiira). Mafupipafupi a kuwala amagwirizana kwambiri ndi mphamvu yomwe imanyamula—mafupipafupi akakwera, mphamvu imakweranso.
Monga tinthu tating'onoting'ono, kuwala kumakhala ndi ma photon, mapaketi ang'onoang'ono a mphamvu omwe alibe kulemera. Lingaliro ili ndi lofunika pofotokoza zochitika monga mphamvu ya photoelectric, momwe kuwala komwe kumagunda pamwamba pa chinthu kumatha kutulutsa ma elekitironi kuchokera mu chinthucho.
Sipekitiramu yamagetsi yamagetsi
Mafunde owala ndi gawo laling'ono chabe la ma electromagnetic spectrum, omwe amaphatikizapo mitundu ina yambiri ya mafunde, monga mafunde a wailesi, ma microwave, ma ray a infrared, ma ultraviolet rays, ma X-ray, ndi ma gamma rays. Kusiyana kwakukulu pakati pa mitundu yosiyanasiyana ya mafunde a electromagnetic ndi kutalika kwa mafunde ndi kuchuluka kwawo.
Kuwala kooneka ndi gawo la ma electromagnetic spectrum omwe diso la munthu limatha kuwazindikira. Lili ndi mitundu isanu ndi iwiri yotchedwa utawaleza: wofiira, lalanje, wachikasu, wobiriwira, wabuluu, indigo, ndi violet. Mtundu uliwonse uli ndi kutalika kosiyana kwa mafunde, pomwe wofiira uli ndi kutalika kwa mafunde kwakutali komanso kotsika kwambiri, pomwe violet ili ndi kutalika kwa mafunde kwakutali komanso kotsika kwambiri.
Kusokoneza ndi Kusokoneza
Zochitika ziwiri zofunika zomwe zimasonyeza momwe kuwala kumakhalira ndi mafunde ndi kusokoneza ndi kufalikira kwa kuwala. Kusokoneza kumachitika pamene mafunde awiri kapena kuposerapo a kuwala akumana ndikusakanikirana, zomwe zimapangitsa kuti kuwala kukhale kowonjezereka (kusokoneza komanga) kapena kuchepa (kusokoneza kowononga) kukhale kowala. Izi zitha kuwonedwa mu kafukufuku wotchuka wa double-slit, pomwe kuwala komwe kumadutsa m'mipata iwiri yopapatiza kumapanga mawonekedwe okhazikika a kuwala ndi mthunzi pazenera kumbuyo kwawo.
Kumbali ina, kusinthasintha ndi kupindika kwa mafunde a kuwala pamene akudutsa mpata wopapatiza kapena akagunda chopinga. Chochitika ichi chimapanga mapangidwe ovuta a kuwala ndi mdima, omwe nthawi zambiri amawonedwa kuwala kukagunda cholumikizira.
Kugawanika kwa Kuwala
Polarization ndi chizindikiro cha mafunde a kuwala komwe mafunde amasinthasintha mbali imodzi. Mafunde achilengedwe a kuwala, monga kuwala kwa dzuwa, sasinthasintha, zomwe zikutanthauza kuti amasinthasintha mbali zosiyanasiyana. Komabe, kudzera mu njira ya polarization, monga kudutsa mu fyuluta ya polarizing, kuwala kumatha kusinthasintha mbali imodzi yokha. Polarization imagwiritsidwa ntchito kwambiri m'magalasi oletsa kuwala ndi ma LCD, komwe kumachepetsa kuwala ndikuwonjezera kusiyana kwa chiwonetsero.
Kugwiritsa Ntchito Mafunde Owala
Mafunde a kuwala ali ndi ntchito zambiri zothandiza pa moyo watsiku ndi tsiku. Chimodzi mwa zofala kwambiri ndi kuyatsa. Nyali zamagetsi zakhala zida zofunika kwambiri zowunikira, zomwe zimatithandiza kuyenda muzochitika zathu usiku. Kuphatikiza apo, mafunde a kuwala amagwiritsidwa ntchito polumikizana ndi fiber-optic, komwe zizindikiro za kuwala zimanyamula deta kudzera mu ulusi wagalasi kapena pulasitiki pa liwiro lalikulu kwambiri.
Mu zamankhwala, ukadaulo wogwiritsa ntchito kuwala monga lasers ndi wofunikira pakuchita opaleshoni yolondola komanso chithandizo cha khansa. Kuphatikiza apo, njira zojambulira zamankhwala monga X-ray ndi MRIs zimadalira mfundo zomwezo za electromagnetic spectrum.
Sayansi ya zakuthambo ndi gawo lina lomwe limapindula kwambiri ndi kuphunzira za kuwala. Kuwala kochokera ku nyenyezi zakutali ndi milalang'amba kumatipatsa chidziwitso chofunikira chokhudza chilengedwe chonse, monga kapangidwe ka mankhwala awo, kutentha, mtunda, ndi kayendedwe kawo. Ma telesikopu omwe amagwiritsa ntchito mitundu yosiyanasiyana ya mafunde a kuwala, kuyambira infrared mpaka X-ray, amathandiza asayansi kuphunzira zinthu zakuthambo mwatsatanetsatane.
Mphamvu ya Mafunde a Kuunika pa Moyo
Mphamvu ya mafunde a kuwala pa moyo singanyalanyazidwe. Kupanga kwa kuwala, njira yofunikira yomwe imalola zomera kukhala ndi moyo ndikupanga mpweya, kumadalira kwathunthu kuwala kwa dzuwa. Pakadali pano, kwa anthu ndi zamoyo zina zambiri, kuwala kumachita gawo lolamulira kayendedwe ka circadian, kapena mawotchi achilengedwe, omwe amakhudza momwe munthu amagona komanso momwe amadzuka.
Kumbali ina, kukhudzana kwambiri ndi mafunde ena a kuwala, monga kuwala kwa ultraviolet, kungakhale ndi zotsatirapo zoipa pa thanzi, monga kuchititsa khansa ya pakhungu. Chifukwa chake, kumvetsetsa mafunde a kuwala ndi zotsatira zake ndikofunikira kwambiri kuti tiwonjezere phindu ndikuchepetsa zoopsa pa moyo.
Mapeto
Mafunde a kuwala ndi chimodzi mwa zodabwitsa kwambiri zachilengedwe komanso maziko a ukadaulo wamakono. Kumvetsetsa kwathu mafunde a kuwala kukupitirira kukula, kupereka chidziwitso chatsopano cha momwe tingagwiritsire ntchito mphamvu zamagetsi kuti tipindule anthu. Kuyambira kuunikira mpaka kulankhulana, kuyambira thanzi mpaka kufufuza mlengalenga, kuthekera kwa mafunde a kuwala kuli kopanda malire. Pamene ukadaulo ukupita patsogolo, pakhoza kukhala njira zambiri zatsopano zomwe mafunde a kuwala angagwiritsidwe ntchito kuti apange dziko labwino komanso lowala.
