Ngezenzeko Sound kwi ziyaphila kunye nohlobo engaphili: imizekelo

Abantu abaninzi bafuna ukufumana iimpendulo kwimibuzo malunga nokuba ziintoni iziphumo zesandi, kwakunye apho zivela. Yintoni basis izandi ezahlukeneyo kwabanye? Kutheni na ke ukuba sibeve nje kubo?

Namhlanje sijonga icandelo physics, ejongisisa isenzeko umgangatho wobudlelwane. Eli candelo kuthiwa umsindo.

Oscillation - unobangela zonke izandi kwi planethi

Ukuba uve isandi, ngoko engqondweni siya unokuthelekelela lo mthombo, apho ishicilela. Ngoko ke, ukuba unobudlelane oko, apho siya kubona ntoni abazali. Xa sithetha, nemitya iyangcangcazela ngaphakathi emzimbeni wethu. Ngenxa yoko, siva ilizwi lakho. Imizekelo ngezenzeko yesandi physics sikubonayo ukuva yonke imihla.

ulwazi zembali

Sasifunda isimo sound physics ukususela kumaxesha amandulo. nabo zethu obungunaphakade ebomini zezona iingxolo nezandi. Kukho ingxolo Iintshukumo ukuba mnandi, abanye ekukruqulayo nathi. Ngala mazwi, sinokugqiba ukuba izandi kunye nezandi neziphumo ezahlukileyo ingqondo kunye nempilo yomntu. Yinto eyaziwayo ukuba ezinye ingxolo umntu hambana-hambana, kwaye kukho izandi na ukuphilisa nasiphi na isifo ebantwini. Ezi ezifunyaniswe umntu ngaphambi kwexesha lethu. Kungekudala emva koko, uyazi, yintoni na iziphumo zesandi. Okwangoku, makhe sithethe ezifunyaniswe kummandla umsindo.

impucuko yamandulo

ukusebenza ukuphiliswa ezimangalisayo yesandi kubabingeleli zabantu waphawula iintlafuno eYiputa yamandulo. Ngokuqhelekileyo, bona into esetyenziselwa iinjongo zenkolo. Ngoku ke amaYiputa isiko amisiweyo ayibanga ngaphandle engqungqa kunye neengoma. Kungekudala emva koko, umculo kunye izandi waziqhawula sele kwiicawa zamaKristu. A inqanaba eliphezulu yesakhono umculo phambi kokuba wonke umntu kakuhle amaNdiya. Emva ngaloo mihla badalelwe ngenkuthalo kusetyenziswa ubhalo lomculo. I AmaNdiya wanika inqaku ngalinye ixabiso ethile. Lokugqibela Uluhlu note "hayi" libhekisela buhlungu, inqaku "Pa" libhekisela luvuyo.

KaPythagoras - uyise nemisindo

Ukususela kumaxesha amandulo, abantu baye bazama ukuhlola isimo isandi. Umzekelo, i-amandulo nzulu yamaGrike sobulumko Pythagoras sezibalo, owayephila 2500 kwiminyaka eyadlulayo, wayeqhuba iintlobo-experimenti ezininzi anezandi. wangqina ukuba ilizwi aphantsi kwezixhobo ikhona kuphela abo imitya elide ngenxa yokuvela yayo. Xa umtya bufinyeziwe ngesiqingatha, kwaye isandi linyuke wenowuthi mnye. Ngenxa ezi ziphumo kaPythagoras yaba ekuqaleni candelo physics - umsindo. Ezi zixhobo yokuqala yiacoustic wadala amaGrike, owayephila kudala. Benza ukuphila kwabo ezinkundleni. Ezi zixhobo ziye ngohlobo iimpondo ezincinane, zezona abadlali kufakwa imaski yakhe ukuphucula isandi. Hi ndlela leyi, kuba isenzeko umdla kakhulu bezikrokrela kwimifanekiso eqingqiweyo oothixo baseYiputa yamandulo.

Renaissance and kukanye

Ukutyhubela iinkulungwane, imisindo saqhubeka nokufunda. Hi xikombiso, le umsindo wayesebenza kude ngumzobi uLeonardo da Vinci. Kwiincwadi zakhe, yena yaqulunqa umgaqo isandi amaza inkululeko evela kwimithombo eyahlukeneyo. Emva kweminyaka 400 eFransi e Paris Academy of Sciences Joseph Saverio epapashwe "Memoirs ze umsindo". Ke Newton iye yafunda imisebenzi Saverio. Ngokusekelwe kwiziphumo zawo kunye nezigqibo, liphuhlise ukubalwa neembono ive. Newton weza wafikelela kwisigqibo sokuba ombala isandi ngokuphindwe kabini ityhubhu evelisa esi sandi.

Ukuzimisela ezinengqondo

Oko kuthetha ngezenzeko isandi? Sichubeka ukuba inkcazo elithi "isandi". Oku intlokoma mechanical leyo ukusasaza kumajelo eendaba ilastiki, ezifana nerhasi, ulwelo kunye eziqinileyo. Iingoma ezipholileyo mechanical enjalo ndiyabona amalungu ezikhalayo, oko kukuthi, ezindlebeni zethu. A umzekelo olula, oluzakuthi luchaze kakuhle eli isandi iya kuba umtya nasiphi na isixhobo somculo. It adlulisele intlokoma ezingqonge amasuntswana emoyeni. Nokunyuka saa kude xa befikelela indlebe, bakufikise intlokoma le indlebe. Ngenxa yoko, nathi ngokwahlukileyo ukuva.

izenzakalo Sound endalweni

Amaza Isandi kubonwa. Noko ke, unako becinga ukuba baya kukhangela ngayo. Ukuze wenze oku, kufuneka uye naliphi umzimba ngamanzi. Ukuba phosela ilitye echibini okanye echibini, ngoko uya kubona lekhefu lokuqala. Amanzi ke ngoko iphakamile, yaye ngaloo ndlela kubonakala phezu yomtshangatshangiso ebusweni dama, ezo khosi alternating yokuxheshisela kunye crests. Baya kuthunyelwa kuwo onke amacala.

Amacandelo umsindo

Imiba ukuvela nokwanda, kunye nesandi yokufunxa sele umsindo. Kule minyaka ili-10 idlulileyo, i umsindo emzimbeni wavula izandi ukuba aphume uyaluthanda wena. izifundo zabo ultrasonics. Technical Acoustics lijongana iinkqubo kokufumana, wayithumela nokurekhodwa ubuchule besebenzisa izixhobo zombane. Icandelo elilandelayo lifunda andise isandi kwelo gumbi - umsindo bokwakha. Kuba kubalulekile nje kuphela ubungakanani kunye nokumila egumbini, apho isandi uphando, kodwa izinto ezisisiphumo iindonga kunye nophahla egumbini. umsindo Musical efundelwa uhlobo imvelaphi izandi zomculo. Sikunye namanye amacandelo, kukho umsindo elwandle (sonar). Iyilelwe ukuba ukufunda ngendima yesandi kokusingqongileyo emanzini. Sonar kubalulekile kuphuhliso, kwakunye nokudalwa nezixhobo zesandi enokusetyenziswa ii nkwili. Kukho uhlobo olunye - le umsindo komoya. Yena ufunda ngumkhuba of yesandi apha emoyeni. Bokuphila Acoustics ungumgcini kwetyala. Ngenxa yakhe siyazi izakhono imizimba yethu, umbutho nesenzo sabo. Olu hlobo lwemfundo ukufunda umsindo intetho omzimba izandi. Ke lowo wokugqibela - yinto umsindo eziphilayo. Ulungisa imiba cuke kunye sonic yonxibelelwano isilwanyana. Kwakhona liphonononga iindawo iindlela ezisetyenziswa zizilwanyana, ukongeza, ukudlulisa eziphilayo eyenzelwe kuphanda ingxaki nengxolo kunye ukungcangcazela, kuyimfuneko ukuba balwe ingxolo eziyingozi kunye nokuphucula okusingqongileyo.

izenzakalo umsindo wemvelo okungaqhelekanga

On iplanethi yethu, kukho iindawo kakuhle yaziwa ngenxa kwizinto ezenzeka ngayo buzz. Uchazwa lomsindo rhoqo nezisezantsi. Lo mthombo esinengqondo okwangoku zifunyenwe. Talas e New Mexico uye onjalo esingaqhelekanga umthombo ephilileyo. Kuyamangalisa ukuba lo hum ivakele% 2 kuphela abahlali balapho, bathi isandi kuyakhathaza kakhulu.

izenzakalo umsindo wemvelo okungaqhelekanga

Enye isandi mntu ezimnandi kakhulu yathi purring cats. Izazinzulu olusafundayo esi senzeko. Imvelaphi yalo sandi azinako ukusekwa nangoku. Akukho ngaphantsi isimanga yendalo zithathwa izandi entsonkothileyo kakhulu elide, ephethe iminenga mnenga eyindoda. Izazinzulu abaninzi bakholelwa ukuba kuyimfuneko kukutsala iimazi, kodwa izifundo kutshanje lubonisa ukuba isandi akukho nokutsala kwamabhinqa namadoda.

Kwindalo, kukho inani elikhulu izandi. Siva kwezulu. Winter phantsi kweenyawo zethu ikhephu egramza. Ukuba ingamemezanga ehlathini, siva lo msindo. It, kakhulu, umzekelo ngezenzeko yesandi endalweni.

Ngenxa yoko, siye ingqalelo imizekelo ngezenzeko isandi physics kanye indalo. Akubangakho namnye umsebenzi lokuhlolwa wena ungoyiki.
