Ihe atụ nke nnyonye anya na mgbasa ozi nke ìhè - diffraction grating

Mụọ ihe atụ nke nsogbu nke nnyonye anya na diffraction nke ìhè - diffraction grating , wee rụọ ọrụ na nsogbu nke nnyonye anya na diffraction nke ìhè.

1. A na-etinye ihe nrịbama diffraction nke nwere ahịrị 4000 kwa 1 cm n'ebe dị anya nke mita 1 site na oghere ahụ a na-enwu gbaa. Gbakọọ ogologo ebili nke ìhè ma ọ bụrụ na onyonyo kachasị elu nke mbụ dị sentimita 30 site na oghere ahụ.
Mkparịta ụka
A maara na:
d = 1 / (ahịrị 4000 / cm) = 0,00025 cm = 2,5 x 10-4 cm = 2,5 x 10-6 m
l = 1m
y = 30 cm = 0,3 m
A jụrụ: ogologo ebili mmiri (lambda)
Azịza:
Akụkụ ahụ dị obere nke na mmehie ahụ dị oke njọ tit Tangent na-abịaru nso tit

Ihe atụ nke nnyonye anya na mgbasa ozi nke ìhè - grating diffraction - 1Nkọwa: nm = nanometer, m = mita

2. A na-eji grating nwere ahịrị 2400/cm ekewapụ ìhè nwere ogologo ebili mmiri nke 540 nm. Chọpụta akụkụ nke abụọ nke diffraction!
Mkparịta ụka
A maara na:
Ogologo ebili mmiri = 540 nm = 540 x 10-9 m = 5,40x10-7 m
d = 1 / (ahịrị 2400/cm) = 0,0004 cm = 4 x 10-4 cm = 4 x 10-6 m
n = 2 (usoro nke abụọ)
A jụrụ: akụkụ nkewa nke usoro nke abụọ (n = 2)
Azịza:
Ihe atụ nke nnyonye anya na mgbasa ozi nke ìhè - grating diffraction - 2

3. A na-eduzi ìhè nwere ogologo ebili mmiri nke 9450 Å n'akụkụ ebe a na-akpọ diffraction grating. Nkwụsịtụ kachasị na-eme n'akụkụ 30°. Ọnụọgụ nke ọkọ na grating kwa cm bụ…
A. oghere 5291
B. oghere 5200
Oghere C. 5560
D. oghere 5650
E. oghere 5670
Mkparịta ụka:

A maara :
Mgbochi nke ìhè, ihe ndọpụ uche - 1A jụrụ :
E nwere ọtụtụ ntụpọ na grid ọ bụla 1 cm.
Jawab :
Mgbochi nke ìhè, ihe ndọpụ uche - 2Ọtụtụ ọkpụ ma ọ bụ oghere dị iche iche kwa 1 cm:
1/18900 x10-8 cm = 5291 strok / cm
Azịza ziri ezi bụ A.

4. A na-eji grating nke nwere ahịrị 2000 kwa cm iji chọpụta ogologo ebili mmiri nke ìhè. Akụkụ dị n'etiti ahịrị etiti na ahịrị nke mbụ bụ 12o (mmehie nke 12)o = 0,208). Kedu ka ogologo ebili nke ìhè ahụ si dị?
A. 10400 Å
B. 10000 Å
C. 9640 Å
D. 9550 Å
E. 8750 Å

Ogologo ebili mmiri?
Jawab :
Mgbochi nke ìhè, ihe ndọpụ uche - 4Azịza ziri ezi bụ A.

Nkwụsị na mgbasa nke ìhè - ihe nkedo diffraction

1. A na-etinye ihe nrịbama diffraction nke nwere ahịrị 3000 kwa 1 cm n'ebe dị anya mita 2 site na oghere ahụ a na-enwu gbaa. Gbakọọ ogologo ebili nke ìhè ahụ ma ọ bụrụ na onyonyo kachasị elu nke mbụ dị cm 20 site na oghere ahụ.
2. A na-eji grating nke nwere ahịrị 2500/cm ekewapụ ìhè nwere ogologo ebili mmiri nke 540 nm. Chọpụta akụkụ nke atọ nke diffraction!
