Phunziro la Microwave la Wonka Donka
Iyi ndi njira ya kuwonongeka kwa Wonka Donka mu ma electromagnetic spectrum ndi ma microwave ovens.
Ma Microwaves ndi gawo la ma electromagnetic spectrum, kuchuluka kwa "kuwala" pama frequency ndi mafunde osiyanasiyana. Kuwala mu nkhani iyi kumatanthauza zonse alternating magetsi ndi maginito minda, kagawo kakang'ono kamene kuwala looneka.Sipekitiramuyi imachokera ku ma radiation okhala ndi mafunde afupikitsa komanso ma frequency apamwamba mpaka kutalika kwa mafunde ndi ma frequency otsika.Gamma ray, X-ray, ultraviolet, zowoneka, infrared, microwave ndi mafunde a wailesi.Ma microwave ali ndi ma frequency otsika komanso kutalika kwa mawonekedwe. Amatchedwa "micro" chifukwa ali ndi utali wamfupi kuposa mafunde a wailesi, osati chifukwa ndi mafunde ang'onoang'ono (micro). Kutalika kwawo kumatha kukhala pakati pa 1 mm ndi 1 m.Ma microwave amagwiritsidwa ntchito kutumiza ma siginecha kuchokera ku ma satellite ndi mafoni am'manja, komanso kutenthetsa chakudya.Uvuni wa microwave, kapena kungoti uvuni wa microwave monga momwe tonse tikudziwira, umapezeka m'nyumba zambiri ndipo ndi njira yachangu komanso yosavuta yotenthetseranso chakudya.Ma radiation a electromagnetic opangidwa ndi uvuni wa microwave amatengedwa ndi mamolekyu amadzi muzakudya. Izi zimapangitsa kuti mamolekyu amadzi agwedezeke ndi kutentha, zomwe zimatenthetsa chakudya chanu.Zoyipa za ma microwave sizimamveka bwino, ndipo palibe zotsatira zanthawi yayitali zowonekera mosalekeza kumagulu otsika zatsimikiziridwa.Mavuni a microwave ali ndi zinthu zingapo zotetezera kuteteza kutayikira kwa radiation ya microwave:2. Khomo la uvuni wa microwave lapangidwa mwapadera kuti lizigwira ntchito pokhapokha litatsekedwa.3. Ma mesh omwe amakulepheretsani kuwona bwino mu microwave ndi njira yodzitetezera. Mabowo a pepala lachitsulo sali aakulu mokwanira kulola ma microwave kudutsa, koma amalola kuwala kowoneka kudutsa.
Ma Microwaves ndi gawo la ma electromagnetic spectrum, kuchuluka kwa "kuwala" pama frequency ndi mafunde osiyanasiyana. Kuwala mu nkhani iyi kumatanthauza zonse alternating magetsi ndi maginito minda, kagawo kakang'ono kamene kuwala looneka.
Sipekitiramuyi imachokera ku ma radiation okhala ndi mafunde afupikitsa komanso ma frequency apamwamba mpaka kutalika kwa mafunde ndi ma frequency otsika.Magawo asanu ndi awiri a radiation mu electromagnetic spectrum:
Gamma ray, X-ray, ultraviolet, zowoneka, infrared, microwave ndi mafunde a wailesi.
Ma microwave ali ndi ma frequency otsika komanso kutalika kwa mawonekedwe. Amatchedwa "micro" chifukwa ali ndi utali wamfupi kuposa mafunde a wailesi, osati chifukwa ndi mafunde ang'onoang'ono (micro). Kutalika kwawo kumatha kukhala pakati pa 1 mm ndi 1 m.
Ma microwave amagwiritsidwa ntchito kutumiza ma siginecha kuchokera ku ma satellite ndi mafoni am'manja, komanso kutenthetsa chakudya.ma microwave
Uvuni wa microwave, kapena kungoti uvuni wa microwave monga momwe tonse tikudziwira, umapezeka m'nyumba zambiri ndipo ndi njira yachangu komanso yosavuta yotenthetseranso chakudya.
Ma radiation a electromagnetic opangidwa ndi uvuni wa microwave amatengedwa ndi mamolekyu amadzi muzakudya. Izi zimapangitsa kuti mamolekyu amadzi agwedezeke ndi kutentha, zomwe zimatenthetsa chakudya chanu.
Zoyipa za ma microwave sizimamveka bwino, ndipo palibe zotsatira zanthawi yayitali zowonekera mosalekeza kumagulu otsika zatsimikiziridwa.Kutentha kwakukulu kwa ma microwave kumakhala ndi zotsatira zofanana pa zamoyo monga momwe zimakhalira pa chakudya; mamolekyu amadzi amatenthetsa ndikukula, kumayambitsa kuyaka.
Mavuni a microwave ali ndi zinthu zingapo zotetezera kuteteza kutayikira kwa radiation ya microwave:1. Ma Microwaves amawonetsedwa ndi zitsulo, kotero mkati mwa uvuni wa microwave amapangidwa ndi chitsulo kuti mukhale ndi kugawa ma radiation. Izi zimathandiza kutenthetsa chakudya mofanana komanso kuteteza ma microwave kuti asatayike.
2. Khomo la uvuni wa microwave lapangidwa mwapadera kuti lizigwira ntchito pokhapokha litatsekedwa.
3. Ma mesh omwe amakulepheretsani kuwona bwino mu microwave ndi njira yodzitetezera. Mabowo a pepala lachitsulo sali aakulu mokwanira kulola ma microwave kudutsa, koma amalola kuwala kowoneka kudutsa.
