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)
Mhinduro:
Kona yacho idiki zvekuti chivi tit kuswedera pedyo tit

Tsananguro: nm = nanometer, m = mita

2. Chiedza chine urefu hwemafungu e540 nm chinokanganiswa negirati ine mitsetse 2400/cm. Sarudza kona ye diffraction yedanho rechipiri!
Kukurukurirana
Zvinozivikanwa kuti:
Hurefu hwemafungu = 540 nm = 540 x 10^-9 m = 5,40 x 10^-7 m
d = 1 / (mitsara 2400/cm) = 0,0004 cm = 4 x 10^-4 masendimita = 4 x 10^-6 m
n = 2 (chikamu chechipiri)
Yakabvunzwa: kona yekudimbura kwechipiri (n = 2)
Mhinduro:

3. Mwenje wechiedza une urefu hwemafungu e9450 Å unonangidzirwa zvakananga pagirafu ye diffraction. Kupindira kwakanyanya kunoitika pakona ye30°. Huwandu hwekukwenya pagirafu pa cm imwe neimwe…
A. 5291 mipata
B. 5200 mipata
Musiyano weC. 5560
D. 5650 mipata
Musiyano weE. 5670
Kukurukurirana:

Zvinozivikanwa :
Akabvunzwa :
Pane mikwaruko yakawanda pagridi yega yega 1 cm.
Jawab :
Makwara akawanda kana mipata pa 1 cm:
1/18900x10^-8 cm = 5291 mitsipa / cm
Mhinduro chaiyo ndiA.

4. Girazi rine mitsetse 2000 pa cm imwe neimwe rinoshandiswa kuona urefu hwechiedza. Kona iri pakati pemutsetse wepakati nemutsetse wekutanga i12^o (chivi 12^o = 0,208). Chii chinonzi urefu hwemafungu echiedza?
A. 10400 Å
B. 10000 Å
C. 9640 Å
D. 9550 Å
E. 8750 Å
Kukurukurirana:
Zvinozivikanwa :
Akabvunzwa :
Kureba kwemafungu?
Jawab :
Mhinduro chaiyo ndiA.

Kupindira uye kupararira kwemibvunzo yakapfava - kupatsanura maburi

1. Girazi re diffraction rine mitsetse 3000 pa 1 cm rinoiswa padaro remamita maviri kubva paburi rakavhenekerwa. Verengai kureba kwechiedza kana mufananidzo wepamusoro we order yekutanga uri 20 cm kubva paburi.
2. Chiedza chine urefu hwemafungu e540 nm chinokanganiswa negirati ine mitsetse 2500/cm. Sarudza kona yediffraction yechikamu chechitatu!
