Simba reMafungu eElectromagnetic: Kutevera Nhoroondo Yaro Kumashandisirwo Aro Pari Zvino
Simba remagetsi rinoshandisa mafungu emagetsi chinhu chakakosha mufizikisi yemazuva ano uye tekinoroji. Kubva kumafungu eredhiyo kusvika kumwaranzi yegamma, electromagnetic spectrum inosanganisira mafungu akasiyana-siyana ane mashandisirwo akasiyana-siyana muhupenyu hwezuva nezuva, indasitiri, nesainzi. Chinyorwa chino chichaongorora zvakadzama simba remagetsi rinoshandisa mafungu emagetsi, kubva papfungwa dzaro dzekutanga kusvika pakushandiswa kwaro kwemazuva ano.
Pfungwa Dzekutanga dzeMafungu eElectromagnetic
Mafungu emagetsi emagetsi anotenderera minda yemagetsi nemagineti inopararira muchadenga. Izwi rekuti "electromagnetic" rinobva muzvikamu zviviri zvikuru zvinoumba mafungu aya: minda yemagetsi (electro) nemagineti (magnetic). Zviviri izvi zvinodyidzana zvichienderana nekuenzanisa kwaMaxwell, uko kunotsanangura kuti munda wemagetsi unoshanduka unoburitsa sei munda wemagetsi, uye zvinopesana.
Mafungu emagetsi haadi chinhu chinofambisa mhepo kuti chipararire, kusiyana nemafungu emagetsi akaita semafungu eruzha, ayo anoda chinhu chinofambisa mhepo semhepo kana mvura. Nekuda kweizvi, mafungu emagetsi anogona kupararira nepaburi remhepo, zvichitibvumira kugamuchira chiedza kubva kuzuva nemasaini eredhiyo kubva muchadenga.
Mafungu aya anotendererawo, zvichireva kuti kutenderera kwawo kunoitika akatarisana nekwakapararira mafungu. Simba remafungu emagetsi rinoyerwa mumaphoton, ayo ari maquanta kana mapaketi madiki esimba remagetsi.
Electromagnetic Spectrum
Chiyero chemagetsi chinosanganisira marudzi akasiyana-siyana emafungu zvichienderana nefrequency kana wavelength yawo. Kubva pamafrequency akaderera kusvika pahigh, ichi chinosanganisira:
1. Mafungu eredhiyo: Anoshandiswa mukutaurirana kusina waya, kusanganisira redhiyo, terevhizheni, uye network dzefoni.
2. Ma microwave: Anoshandiswa mu radar, ma microwave oven, uye tekinoroji yekutaurirana iri kure.
3. Infrared: Inoburitswa nezvinhu zvinoburitsa kupisa uye zvinoshandiswa muzvinodzora zviri kure uye muzvinzwa zveinfrared.
4. Chiedza Chinooneka: Rudzi rudiki rwe electromagnetic spectrum runogona kuonekwa neziso remunhu. Izvi zvinosanganisira mavara ese kubva kutsvuku kusvika kuviolet.
5. Ultraviolet: Inoburitswa nezuva uye inoshandiswa muhunyanzvi hwekurapa nemwenje.
6. X-rays: Inoshandiswa mukuongororwa kwechiremba nekuchengetedzwa.
7. Gamma Rays: Inoshandiswa mukurapa nemwaranzi uye mukutsvaga kwesainzi.
Chikamu chimwe nechimwe chespectrum chine hunhu hwacho uye mashandisirwo acho zvichienderana nefrequency yacho uye wavelength.
Nhoroondo yeKuwanikwa kweMafungu eElectromagnetic
Kuwanikwa kwemafungu emagetsi kwakakonzerwa nemabasa evasayendisiti vakawanda. James Clerk Maxwell aive munhu akakosha mukugadzira maequation aMaxwell pakati pezana remakore rechi19, achitsanangura hwaro hwedzidziso yemagetsi. Heinrich Hertz akazoratidza kuvapo kwemafungu emagetsi kuburikidza nekuyedza muna 1887, zvichigadzira nzira yekuvandudzwa kwetekinoroji yemazuva ano yekutaurirana.
Maxwell akabatanidza pfungwa dzemagetsi nemagnetism kuita dzidziso imwe chete, yakazara yakaratidza kuti chiedza pachacho imhando yemafungu emagetsi. Kuwanikwa uku hakuna kungochinja chete kunzwisisa kwedu chiedza asiwo kwakatungamira mukuvandudzwa kwemhando dzakasiyana dzematekinoroji matsva akavakirwa pamafungu eredhiyo nedzimwe mhando dzemafungu emagetsi.
Mashandisirwo eElectromagnetic Wave Energy
Munguva yazvino, simba remafungu emagetsi rine mashandisirwo akasiyana-siyana. Mamwe acho anosanganisira:
Telekomunikasi
Redhiyo nema microwave zvinoshandiswa zvakanyanya mukutaurirana. Redhiyo, terevhizheni, nharembozha, uye internet isina waya mienzaniso mikuru inoratidza kuti mafungu emagetsi anorerutsa sei kutaurirana kwemazuva ano. Mu tekinoroji yefoni, masaini eredhiyo ane frequency yakakwira anoshandiswa kutumira nekugamuchira data, zvichigonesa kubatana kwepasi rose kwatinofarira nhasi.
Medical
Mukurapa, maX-ray nemagamma rays anoshandiswa pakuongorora nekurapa chirwere. MaX-ray anobvumira vanachiremba kuona zvivako zvemukati memuviri vasina kuvhiyiwa, ukuwo magamma rays achishandiswa pakurapa nemwaranzi kuuraya masero ekenza.
Maindasitiri neTekinoroji
Muindasitiri netekinoroji, mafungu e infrared anoshandiswa mumasensa ekuona kupisa kana kufamba. Ma microwave anoshandiswa mumaovheni kupisa chikafu nekukurumidza uye zvinobudirira. Ma laser, ayo ari marudzi emagetsi akatarisana, anoshandiswa mukushandiswa kwakasiyana-siyana kubva pakunamira kusvika pakuvhiyiwa kwemaziso.
Kutsvaga Nyeredzi neZvinhu Zvemuchadenga
Mukuongorora nyeredzi, zvikamu zvakasiyana-siyana zve electromagnetic spectrum zvinoshandiswa kuona nekudzidza muchadenga. Semuenzaniso, materesikopu eredhiyo anoshandiswa kuona mafungu eredhiyo kubva kuzvinhu zviri kure zvakaita se pulsars nemagalaxy. Materesikopu e infrared anoshandiswa kuona kuburikidza nemakore eguruva remuchadenga anovhara chiedza chinoonekwa.
Kuchengetedzeka uye Migumisiro Yehutano
Pasinei nemabhenefiti ayo akawanda, simba remagetsi rinopawo njodzi. Kunyanya kubatwa nemafungu emagetsi ane simba guru, akadai seX-rays negamma rays, kunogona kukuvadza tishu dzemuviri uye kukonzera kenza. Nokudaro, kushandiswa kwetekinoroji inoburitsa mafungu emagetsi kunofanirwa kutevedzera nzira dzakasimba dzekuchengetedza.
Mitemo ine chekuita nekusangana nemafungu emagetsi yave kushandiswa munyika dzakawanda kudzivirira veruzhinji kubva mukukuvadzwa kunogona kuitika. Semuenzaniso, miganhu yekusangana nemwaranzi yeredhiyo inotariswa zvakanyanya mukuvakwa kwenharembozha nezvimwe zvishandiso zvisina waya.
Remangwana reMafungu eElectromagnetic
Tsvagiridzo mumunda wemafungu emagetsi inoenderera mberi nekukurumidza, paine mukana wekubudirira kwakasiyana-siyana kwetekinoroji mune ramangwana. Imwe nzvimbo ine tariro ndeye "metamaterials," uko zvinhu zvakagadzirwa nehunyanzvi zvinogona kushandisa mafungu emagetsi nenzira dzisingagoneki nezvinhu zvechisikigo. Izvi zvinogona kutungamira mukuvandudzwa mukugadzirwa kwe "invisibility cloaks" kana zvishandiso zvemaziso zvakanyanyisa.
5G pamwe nekukwanisa kwe6G kutaurirana tekinoroji zvinoratidzawo kuti mafungu emagetsi anoshandiswa sei kuwedzera kumhanya kwedata risina waya uye kugona kwayo. Uyezve, kuvandudzwa kwesimba rinogona kuvandudzwa, senge masero ezuva anoshanda zvakanyanya, kunobatsirawo kunzwisisa electromagnetic spectrum.
Mhedziso
Simba remagetsi rinoshandisa mafungu emagetsi ndeimwe yenheyo dzesainzi netekinoroji dzinotsigira zvinhu zvakawanda zvehupenyu hwemazuva ano. Kubva pakutaurirana kusvika kumishonga, kubva kumaindasitiri kusvika pakutsvagisa kwesainzi, simba rayo rakakura uye rakakura. Nekunzwisisa kuri kuramba kuchikura, ramangwana remafungu emagetsi rinotaridzika rakajeka, richivimbisa hunyanzvi hutsva uye matekinoroji anogona kushandura mararamiro edu uye kudyidzana nenyika. Kunzwisisa kwakadzama uye kutonga kwakachenjera kwesimba iri kuchaita kuti tigone kurishandisa zvakanaka uku tichideredza njodzi dzaro.
