Usati wadzidza nezvema lenzi ane convex, tanga wanzwisisa mitemo inotevera yezviratidzo zve convex lenzi.
Mitemo yeZviratidzo zveConvex Lens
- Daro rechinhu (s)
Kana chinhu chikapfuudzwa nepakati, chiedza chinopinda daro rechinhu zvakaratidza kuti zvine mhedzisiro yakanaka.
- Kureba kwemufananidzo (s')
Kana chiedza chikapfuura nemumumvuri, ipapo daro remumvuri yakaratidzwa kuti yakanaka (mufananidzo chaiwo). Kana mufananidzo usina kupfuudzwa nechiedza, ipapo daro remumvuri chiratidzo chisina kunaka (mufananidzo chaiwo).
- Kureba kwefocal (f)
Kana nzvimbo yekutarisa yelenzi yapfuudzwa nepakati pechiedza, ipapo kureba kwefocal Lenzi yacho inoratidzwa seyakanaka. Kusiyana neizvi, kana nzvimbo yakatarisana nelenzi isina kupfuudzwa nechiedza, ipapo kureba kwefocal Lenzi yacho yakanyorwa kuti haina kunaka. Nzvimbo yakatarisana nelenzi ine convex inopfuudzwa nechiedza, saka kureba kwefocal Lenzi yakamoneredzwa ine kunaka.
- Kureba kwechinhu (h)
Kana chinhu chacho chiri pamusoro pe axis ye convex lens saka kukwirira kwechinhu chacho chiratidzo chakanaka (chinhu chakamira). Kusiyana neizvi, kana chinhu chacho chiri pasi pe axis ye lenzi yakatenderedza musoro saka kukwirira kwechinhu chacho chiratidzo chekuramba (chinhu chakapindurwa).
- Kureba kwemumvuri (h')
Kana mufananidzo uri pamusoro pe axis ye convex lens saka kukwirira kwemumvuri chiratidzo chakanaka (mufananidzo wakatwasuka). Kana mufananidzo uri pasi pe axis ye lenzi yakatenderedza ipapo kukwirira kwemumvuri chiratidzo chisina kunaka (mufananidzo wakapindurwa).
- Kukura kwemufananidzo (m)
Kana kukura kwemufananidzo > 1 zvinoreva kuti saizi yemufananidzo yakakura kupfuura saizi yechinhu. Kana kukura kwemufananidzo = 1 zvinoreva kuti saizi yemufananidzo yakafanana nehukuru hwechinhu. Kana kukura kwemufananidzo < 1 zvinoreva kuti saizi yemufananidzo idiki pane saizi yechinhu.
Fomura yeLenzi yeConvex
Tarisa mufananidzo uri pazasi. Kune mwenje miviri yechiedza inoratidzwa ichienda kune lenzi ine convex, ipapo mwenje yechiedza inodzorwa ne lenzi ine convex.
Mashoko ekuwedzera:
s = daro rechinhu, s' = daro remufananidzo, h = P P' = kukwirira kwechinhu, h' = Q Q' = kukwirira kwemufananidzo, F1 uye F2 = nzvimbo yekutarisa yelenzi ine denderedzwa.
Muchiedza cheP'AQ', triangle P'AP yakafanana netriangle Q'AQ. Saka:
Muchiedza chemwenje P'BF 2 Q', triangle BF 2 A = Q'F 2 Q apo daro AB = kukwirira kwechinhu (h) uye daro F 2 A = kureba kwefocal (f) kwelenzi ye convex. Saka:
Mativi ekuruboshwe nekurudyi eequations 1 ne2 akaenzana, saka mativi ekurudyi akaenzana:
Wedzera mativi ese ari maviri e equation na s' :
Tsananguro yefomura:
s = daro rechinhu (zvakanaka kana chinhu chacho chakapfuudzwa nechiedza chechiitiko)
s' = mumvuri kure (zvakanaka kana mumvuri wakapfuudzwa nechiedza kana mumvuri uri wechokwadi)
f = kureba kwefocal (kwakanaka kana mwenje wechiedza ukapfuura nepakati pefocal lens)
Gara uchiyeuka mutemo wechiratidzo chelenzi ine convex paunenge uchishandisa fomura iyi kugadzirisa matambudziko elenzi ine convex.
Kukura Kwemufananidzo (m)
Tarisa mufananidzo wekuumbwa kwemumvuri wechinhu chiri pamusoro apa. Matriangles PAP' naQAQ' akafanana, saka tinogona kuwana hukama huripo pakati pedaro rechinhu nedaro remumvuri nekukwirira kwechinhu nekukwirira kwemumvuri:
Fomura iri pamusoro inogona kunyorwazve sezviri pazasi nekuwedzera chiratidzo m:
Information :
m = kukura kwemufananidzo
h = kureba kwechinhu (kwakanaka kana chinhu chiri pamusoro pechikamu chikuru chelenzi yakatenderedza kana chinhu chakamira)
h' = kureba kwemufananidzo (kunge mufananidzo uri pasi pechikamu chikuru chelenzi ye convex kana mufananidzo wacho wakapindurwa)
s = daro rechinhu (zvakanaka kana chinhu chacho chapfuudzwa mwenje wechiedza unouya)
s' = daro remufananidzo (rakanaka kana mufananidzo wapfuura nepakati chiedza chemwenje kana mufananidzo chaiwo)
Mibvunzo yemuenzaniso weConvex Lens
Dzidza muenzaniso wemibvunzo ye convex lens kuitira kuti unzwisise zviri nani mashandisirwo emhando ye convex lens.
Mibvunzo Yekudzidzira Nemagirazi EConvex
Zviite mibvunzo yekudzidzira lenzi ye convex kuitira kuti uve nehunyanzvi hwekugadzirisa matambudziko e convex lens.
