Muenzaniso wekupindira uye kupararira kwechiedza - kupatsanurwa kwegedhi

Dzidzai mienzaniso yematambudziko ekupindirana nekupararira kwechiedza - diffraction grating , mobva mashanda pamatambudziko ekupindirana nekupararira kwechiedza.

1. Girazi re diffraction rine mitsetse 4000 pa 1 cm imwe neimwe rinoiswa padaro remita imwe kubva paburi rakavhenekerwa. Verengai urefu hwemwenje wechiedza kana mufananidzo wekutanga uri 30 cm kubva paburi.
Kukurukurirana
Zvinozivikanwa kuti:
d = 1 / (mitsara 4000 / cm) = 0,00025 cm = 2,5 x 10^-4 masendimita = 2,5 x 10^-6 m
l = 1 m
y = 30 cm = 0,3 m
Akabvunzwa: kureba kwehurefu (lambda)

Mienzaniso yemibvunzo pamusoro pekumhanya kweavhareji uye kumhanya kweavhareji - 1

Kureba = mamita zana + mamita makumi mashanu = mamita zana nemakumi mashanu
Huwandu hwekutama = mamita zana - mamita makumi mashanu = mamita makumi mashanu uye divi rekutama riri kumabvazuva.
Nguva yese = masekondi mana + sekondi imwe = masekondi mashanu.

Mienzaniso yemibvunzo pamusoro pedaro uye kutama

4 Mienzaniso yemibvunzo yekureba uye yekutama

1. Mota inofamba yakananga kumabvazuva kwemamita zana yozofamba yakananga kumadokero kwemamita makumi mashanu. Sarudza daro uye kufamba kwemota kubva panzvimbo yayo yekutanga.
Kukurukurirana
Muenzaniso wemibvunzo yekureba uye yekutama - 1 Kureba = mamita zana + mamita makumi mashanu = mamita zana nemakumi mashanu
Huwandu hwekutama = mamita zana - mamita makumi mashanu = mamita makumi mashanu uye divi rekutama riri kumabvazuva.

Muenzaniso wekufamba kwakarongeka kwakafanana

Mienzaniso gumi yekufamba kwakarongeka kwakafanana

1. Mota inotanga yakamira. Mushure memasekonzi mashanu, kumhanya kwemota kunowedzera kusvika 20 m/s. Sarudza kuti mota yacho inomhanya zvakadii!
Kukurukurirana
Hapana fomura (shandisa pfungwa) :
Kumhanya kwemotokari kunochinja kuita 20 m/s mushure memasekonzi gumi. Izvi zvinoreva kuti kumhanya kwemotokari kunowedzera ne2 m/s sekondi yega yega. Saka, kumhanya kwemotokari kuri 2 m/s pasekondi = 2 m/s pasekondi = 2 m/s².
Kushandisa fomura :
Zvinozivikanwa kuti:
Kumhanya kwekutanga (v)_o) = 0 (mota haichinji)

Mienzaniso yemibvunzo yekufamba kwakananga yakafanana

Mienzaniso 7 yeMatambudziko Ekufamba Kwakafanana

1. Mudhudhudhu unofamba wakatwasuka uchimhanya 10 m/s. Sarudza daro rakafambwa nemudhudhudhu mushure memasekonzi gumi nemasekonzi makumi matanhatu.

Kukurukurirana
Kumhanya kwakasimba = 10 m/s kana 10 metres pasekondi zvinoreva kuti mudhudhudhu unofamba mamita gumi pasekondi imwe chete.
Mushure memasekonzi mashanu, mudhudhudhu unofamba mamita makumi mashanu,
Mushure memasekonzi mashanu, mudhudhudhu unofamba mamita makumi mashanu,
