Chitsanzo cha kusokoneza ndi kufalikira kwa kuwala - kugawa kwa kuwala

Phunzirani zitsanzo za mavuto okhudza kusokoneza ndi kufalikira kwa kuwala - kugawa kwa kuwala , kenako gwirani ntchito pa mavuto okhudza kusokoneza ndi kufalikira kwa kuwala.

1. Cholumikizira cha diffraction chokhala ndi mizere 4000 pa 1 cm iliyonse chimayikidwa pa mtunda wa mita imodzi kuchokera pa mpata wowala. Werengani kutalika kwa kutalika kwa kuwala ngati chithunzi choyamba chili pa 30 cm kuchokera pa mpata.
Zokambirana
Amadziwika kuti:
d = 1 / (mizere 4000 / cm) = 0,00025 cm = 2,5 x 10^-4 masentimita = 2,5 x 10^-6 m
l = 1 m
y = 30 cm = 0,3 m
Anafunsa: kutalika kwa nthawi (lambda)
Yankho:
Ngodya yake ndi yaying'ono kwambiri moti uchimo titi kuyandikira tangent titi

Kufotokozera: nm = nanometer, m = mita

2. Kuwala komwe kuli ndi mafunde a 540 nm kumasokonezedwa ndi grating yomwe ili ndi mizere 2400/cm. Dziwani ngodya ya diffraction ya ola lachiwiri!
Zokambirana
Amadziwika kuti:
Kutalika kwa mafunde = 540 nm = 540 x 10^-9 m = 5,40 x 10^-7 m
d = 1 / (mizere 2400/cm) = 0,0004 cm = 4 x 10^-4 masentimita = 4 x 10^-6 m
n = 2 (dongosolo lachiwiri)
Yofunsidwa: ngodya ya diffraction ya dongosolo lachiwiri (n = 2)
Yankho:

3. Kuwala kowala komwe kuli ndi kutalika kwa mafunde a 9450 Å kumayikidwa molunjika pa grating ya diffraction. Kusokoneza kwakukulu kumachitika pa ngodya ya 30°. Chiwerengero cha mikwingwirima pa grating pa cm imodzi ndi…
A. Mipata 5291
B. mipata 5200
C. 5560 kusiyana
D. Mipata 5650
Mpata wa E. 5670
Kukambirana:

Ndizodziwika kuti :
Anafunsa :
Pali mikwingwirima yambiri pa gridi iliyonse 1 cm.
Yankhani :
Mikwingwirima kapena mipata yambiri pa 1 cm:
1/18900 x10^-8 cm = 5291 mikwingwirima / cm
Yankho lolondola ndi A.

4. Chingwe chokhala ndi mizere 2000 pa cm1 chimagwiritsidwa ntchito kudziwa kutalika kwa mafunde a kuwala. Ngodya pakati pa mzere wapakati ndi mzere woyamba ndi 12^o (tchimo 12^o = 0,208). Kodi kutalika kwa mafunde a kuwala ndi kotani?
A. 10400 Å
B. 10000 Å
C. 9640 Å
D. 9550 Å
E. 8750 Å
Kukambirana:
Ndizodziwika kuti :
Anafunsa :
Kutalika kwa mafunde?
Yankhani :
Yankho lolondola ndi A.

Kusokoneza ndi kufalikira kwa mafunso opepuka - kugawa kwa diffraction

1. Cholumikizira cha diffraction chokhala ndi mizere 3000 pa 1 cm chimayikidwa pa mtunda wa mamita awiri kuchokera pa mpata wowala. Werengani kutalika kwa kutalika kwa kuwala ngati chithunzi chachikulu cha oda yoyamba chili 20 cm kuchokera pa mpata.
2. Kuwala komwe kuli ndi mafunde a 540 nm kumasokonezedwa ndi grating yomwe ili ndi mizere 2500/cm. Dziwani ngodya ya diffraction ya gulu lachitatu!
