Fomura Yekukurumidza Kwekuparadzira Mafungu
Mafungu chinhu chinoratidza mafambiro esimba kuburikidza nechinhu chisina kutamiswa zvachose kwezvinhu. Mafungu anogona kuitika mumhando dzakasiyana-siyana, dzakadai semafungu eruzha, mafungu echiedza, mafungu emvura, uye mafungu emagetsi. Chimwe chinhu chakakosha pakudzidza mafungu kumhanya kwemafungu, inova kumhanya kunoita mafungu kuburikidza nechinhu ichi.
Kunzwisisa Kukurumidza Kwekupararira Kwemafungu
Kumhanya kwemafungu, kana kuti kumhanya kwemafungu, idaro rinofambwa nechikamu chemafungu kana gomba muchikamu chenguva. Kumhanya kwemafungu kunowanzo ratidzwa nebhii \( v \) uye kunogona kuyerwa mumamita pasekondi (m/s).
Fomura yekutanga inoshandiswa kuverenga kumhanya kwekupararira kwemafungu ndeiyi:
\[ v = \frac{d}{t} \]
dimana:
– \( v \) ndiko kumhanya kwekuparadzira mafungu,
– \( d \) idaro rinofambwa nemafungu,
– \(t \) inguva inodiwa kuti upfuure daro iroro.
Zvisinei, kana tichitarisa mafungu, tinowanzo shandisa imwe fomura inonyanya kukosha, inoti:
\[ v = f \lambda \]
dimana:
– \( v \) ndiko kumhanya kwekuparadzira mafungu,
– \( f \) ndiyo frequency yemafungu (nhamba yemafungu anopfuura poindi yakapihwa panguva imwe neimwe),
– \( \lambda \) ndiyo wavelength (daro riri pakati penzvimbo mbiri dziri pedyo dzine chikamu chimwe chete, senge misoro miviri kana mipata miviri).
Mafungu eMichina
Mafungu emakanika mafungu anoda chinhu chinofambisa mashoko kuti chipararire, senge mafungu eruzha nemafungu emvura. Kumhanya kwemafungu emakanika kunokanganiswa zvakanyanya nemaitiro echinhu chinofambisa mashoko. Semuenzaniso, kumhanya kwemafungu eruzha mumhepo kwakasiyana nekumhanya kwemafungu eruzha mumvura kana simbi.
Kumhanya kwekupararira kwemafungu patambo, semuenzaniso, kunogona kuverengerwa uchishandisa fomura:
\[ v = \sqrt{\frac{F}{\mu}} \]
dimana:
– \( v \) ndiko kumhanya kwekupararira kwemafungu patambo,
– \( F \) ndiko kushushikana kuri mutambo,
– \( \mu \) huremu hwetambo pahurefu hweyuniti imwe neimwe.
Mafungu Eruzha
Mafungu eruzha rudzi rwemafungu emakanika anopararira kuburikidza nechinhu chakadai semhepo, mvura, kana zvinhu zvakasimba. Kumhanya kweruzha kunoenderana zvakanyanya nepakati netembiricha. Semuenzaniso, kumhanya kweruzha mumhepo pa20°C kunenge 343 m/s.
Fomura inowanzoshandiswa pakuverenga kumhanya kweruzha ndeiyi:
\[ v = \sqrt{\frac{B}{\rho}} \]
dimana:
– \( v \) ndiko kumhanya kweruzha,
– \( B \) ndiyo modulus huru yepakati,
– \( \rho \) ndiko kuwanda kwepakati.
Mafungu eElectromagnetic
Mafungu emagetsi, sechiedza, haadi chinhu chinofambisa mashoko kuti afambe. Mafungu aya anogona kupararira nepamuchina unodzivirira mhepo. Kumhanya kwechiedza mupamuchina unodzivirira mhepo chinhu chinoramba chiripo chinomiririrwa ne \( c \) uye chine kukosha kweinenge 299.792.458 m/s.
Kune mafungu emagetsi ari pakati nepakati, kumhanya kwemafungu kunogona kuonekwa uchishandisa refractive index yepakati (\( n \)):
\[ v = \frac{c}{n} \]
dimana:
– \( v \) ndiko kumhanya kwekupararira kwemafungu pakati,
– \( c \) ndiko kumhanya kwechiedza mu vacuum,
– \( n \) ndiyo chiratidzo chekurefractive chechinhu chiri pakati nepakati.
Kushandiswa kweWave Propagation Speed Formula
Kuziva kumhanya kwemafungu kwakakosha pakushandiswa kwakasiyana-siyana, mune zvesainzi netekinoroji. Heano mimwe mienzaniso yekushandiswa kwefomura yekumhanya kwemafungu:
1. Kutaurirana: Redhiyo nema microwave zvinoshandiswa pakutaurirana kusina waya. Kuziva kumhanya kwekuparadzira mafungu kunobatsira pakugadzira masisitimu ekutaurirana anoshanda.
2. Zvekurapa: Mafungu eUltrasonic anoshandiswa mumifananidzo yezvekurapa, senge ultrasonography. Kumhanya kwemafungu eUltrasonic munyama yemuviri kunobatsira pakugadzira mifananidzo chaiyo.
3. Seismology: Kudzidza nezvekudengenyeka kwenyika kunosanganisira kuongorora mafungu ekudengenyeka kwenyika. Kumhanya kwemafungu aya kuburikidza nezvikamu zvakasiyana-siyana zvePasi kunobatsira masayendisiti kunzwisisa chimiro chemukati mePasi.
4. Kurira kwenzwi: Kugadzirwa kwemakamuri ekuridza mimhanzi, akadai semastudio emimhanzi kana ma theatre, kunoda ruzivo rwekumhanya kwenzwi kuti ruwedzere kunaka kwenzwi.
Zvinhu Zvinokanganisa Kumhanya Kwekupararira Kwemafungu
Zvinhu zvinoverengeka zvinogona kukanganisa kumhanya kwekupararira kwemafungu zvinosanganisira:
1. Rudzi rweMedium: Kumhanya kwemafungu kunosiyana zvichienderana nemedium inopararira mafungu. Semuenzaniso, mafungu eruzha anopararira nekukurumidza mumvura kupfuura mumhepo.
2. Tembiricha: Mune zvimwe zvinhu zvakaita semhepo, kumhanya kwekufamba kwemafungu kunogona kuwedzera nekupisa kuri kuwedzera. Izvi zvinokonzerwa nekuwedzera kwesimba remagetsi remamorekuru ari pakati nepakati.
3. Kuwanda uye Kureba kweMafungu: Kunyangwe fomura \( v = f \lambda \) ichiratidza hukama huripo pakati pekumhanya kwemafungu, frequency, uye wavelength, zvakakosha kuziva kuti shanduko muhuwandu kana wavelength inogona kukanganisa kuti mafungu anopararira sei kuburikidza neimwe nzira.
4. Kusimba uye Kuwanda: Kune mafungu emuchina ari mutambo kana muchitubu, kusimba uye kuwanda kwechinhu chinofambisa mvura zvine basa rakakosha pakuona kumhanya kwekupararira kwemafungu.
Mhedziso
Kumhanya kwemafungu ipfungwa yakakosha mufizikisi yemafungu inotsanangura kumhanya kunofamba simba remafungu nepakati. Nekushandisa fomura \(v = f \lambda \) uye nekufunga nezvezvinhu zvakasiyana-siyana zvinokanganisa kumhanya kwemafungu, tinogona kunzwisisa nekushandisa misimboti iyi muzvikamu zvakasiyana zvesainzi netekinoroji. Kunzwisisa kumhanya kwemafungu hakungobatsiri mukutsvaga dzidziso chete asiwo mukushandiswa kunobatsira mukufambira mberi kwetekinoroji nesainzi.
