Ko wavelength

Muviri vibrating iri kwakavharwa nenyama unosvikirwa, anosika nyonganyonga iri chinopfuudzwa kubva imwe neimwe, uye inonzi chinozunguzirwa. Izvi zvinoitika imwe zvazvingava, izvo vaiona kumhanya vayo kupararira. Ndicho chinhu chinokosha kunozivisa daro vaifamba chero pfungwa chinozunguzirwa chete chikwata rebei.

Regai wave chinokambaira mumwe akabatana (semuenzaniso, chinjikira). chimiro chawo inodzokororwa mune nzvimbo pamusoro kwenguva, t. E. The chinozunguzirwa Profile chinokambaira kupararira akabatana ane velocity ane kugara ukoshi. Over nguva chaienzanirana nguva oscillation, pamupendero wayo misha kure, kunzi wavelength.

Saka, wavelength - chete kure, iro "Zara" zviri mberi kwayo panguva penguva akaenzana nguva oscillation. Kuona wave muchimiro nayo kakawanda vanotaurwa muna nenhamba. Tose rangarirai Zvinoonekwa Somuenzaniso, gungwa mafungu. Mhepo painosunda navo gungwa, uye mumwe chinozunguzirwa ane penyika (matunhu pfungwa) uye yakadereresa pfungwa (kanenge), uye avo uye vamwe yairamba ichifambira uye kushandura mumwe. Pfungwa avete rimwe danho, - the vertices maviri pedyo crests (Ona kubvuma kuti anooneka zvikuru nemichinjiziri zvakafanana pakakwirira uye rakaramba riri kugara kumhanya), kana kuti mbiri yepasisa zvakatinakidza pedyo nemafungu. Wavelength - ndizvo daro pakati pfungwa dzakadaro (mbiri pedyo crests).

Muchimiro mafungu anogona kuparadzira zvose marudzi simba - kupisa, chiedza, ruzha. Vose vane zvakasiyana yakareba. Somuenzaniso, achipfuura muchadenga, kurira mafungu kuchinja mhepo nevezera zvishoma. Categories dzinoenderana maxima ari kunonyanyisa kwokudzvinyirira kwomunhu ruzha. Nokuda kwayo mamiriro, vanhu nzeve otora ndachinja kuitiswa uye anotumira anonongedzera kuuropi. Saka isu kurira.

Ruzha chinozunguzirwa urefu inosarudza ehupfumi kwayo. Kuti tiwane zvakakodzera chinozunguzirwa nokukurumidza (akayera mu m / chik) yakakamurwa kakawanda muna Hz. Muenzaniso: kakawanda 688 Hz mutsindo chinozunguzirwa inofamba pamwero wenyika 344 m / chik. The wavelength achabva akaenzana 344: 688 = 0.5m zvinozivikanwa kuti chinozunguzirwa velocity iri chete ezvinhu haachinji, saka, kureba kwayo achavaponesa kakawanda .. Low-Frequency ruzha vane wavelength anopfuura kumusoro.

Muenzaniso mumwe kusiyana pamusoro remagetsi mwaranzi inogona chiedza chinozunguzirwa. Light - chikamu remagetsi chakarondedzera, zvinoonekwa kuti ziso. The wavelength chiedza kuti ziso munhu anogona kuziva, ari siyana kubvira 400 kusvika 700 nm (nanometers). On kana divi anooneka siyana chakarondedzera nhema munda, musatora ziso redu.

Ultraviolet mafungu vane kureba isingasviki kureba rinooneka chakarondedzera. Nepo ziso munhu anogona kuona navo, asi, zvakadaro, vanogona kukuvadza zvikuru kwedu pake.

The wavelength pamusoro michini mwaranzi kupfuura kufadza pakureba kuti tinogona kuona. Mafungu izvi vanobatwa nenzira chaiyo midziyo uye anoshandiswa Somuenzaniso, chiratidzo usiku kamera.

Pakati nemwaranzi kuwanikwa chiratidzo chedu, zviduku kureba danda rine Violet ruvara, chinonyanya - tsvuku. Pakati pavo nhema yose-siyana iripo maonero (rangarira yomuraraungu!)

Sei tinoona ruvara? Mwaranzi yechiedza ane akafanorongerwa urefu, kuwira pamusoro the retina, ane chiedza-tisanzwe receptors. receptors izvi wokushandura anonongedzera zvakananga mu pfungwa dzedu, apo kutekenyedzwa womumwe ruvara aumbwa. Chii ruvara tinoona - nayo kunoenderana wavelength yacho chiitiko mwaranzi, uye kupenya ruvara manzwiro iri pakutsvaga kusimba nemwaranzi.

All zvinhu zvakatipoteredza kukwanisa kuratidza, zvinoparadzira kana tibatsirwe chiitiko chiedza (zvakakwana kana zvisina kukwana). Somuenzaniso, une mashizha mutema zvinoreva kuti kuwanda yose yairatidza nemwaranzi iri kunyanya mutema mukati ruvara, vamwe vari kunyura. Transparent zvinhu vane tsika kunonotsa akabuda imwe urefu rinoshandiswa Somuenzaniso, mune mufananidzo (kushandiswa mufananidzo filters).

Saka, ruvara chinhu rinotitaurira kukwanisa kuratidza mafungu mumwe chikamu chakarondedzera. Zvinhu anoratidza yose chakarondedzera, tinoona chena, kuchipedza mwaranzi zvose - vatema.
