La weydiiyay: Masaafada ugu dhow ee qofku arki karo isagoon muraayado lahayn

Jawaab:

Muraayad qaloocan mise muraayad qaloocan?

Awoodda muraayadda waa mid togan, sidaa darteed muraayadda la isticmaalay waa muraayad togan, oo loo yaqaan muraayad convex ah, oo sidoo kale loo yaqaan muraayad isku dhafan.

Waa maxay dhererka diiradda ee muraayadda?

P = 1/f

2 = 1/f

f = 1/ 2 = 0,5 mitir = 50 cm

Dhererka diiradda ee muraayadda qaloocan waa 50 cm.

Aragti dhow mise aragti fog?

Haddii muraayadda la isticmaalayo ay tahay muraayad qaloocan, markaas waa muraayad aan la arki karin.

Waa maxay masaafada ugu dhow ee ishu arki karto iyada oo aan lahayn muraayado?

Barta u dhow isha caadiga ah waa 25 cm. Si isha ay u aragto shay meel fog oo 25 cm ah sida isha caadiga ah, muraayaddu waa inay sameysaa sawir masaafad x cm ah oo ku taal muraayadda horteeda. Sawirku wuxuu ku yaal hortiisa muraayadda qaloocan si sawirku u noqdo mid toosan oo casri ah. Sawirku waa mid casri ah, sidaas darteed masaafada sawirka (yada) waa mid taban.

-1/s' = 1/f – 1/s

-1/s' = 1/50 – 1/25 = 1/50-2/50 = -1/50

-s' = -50/1 = -50 cm = -0,50 mitir

s' = 50 cm = 0,5 mitir

Barta u dhow isha caadiga ah waa 25 cm, halka barta u dhow bukaanka ay tahay 50 cm. Taas macnaheedu waa in qofku uu ku adag yahay inuu arko meel u dhow, xaalad loo yaqaan aragti fog. Aragga fog waxaa lagu sixi karaa muraayad qaloocan, sida ka muuqata sawirka hoose.

Si shay loogu arko masaafad dhan 25 cm oo horta isha ah, muraayaddu waa inay sawir ka sameysaa masaafad dhan 50 cm oo horta isha ah iyo muraayadda. Sawirku waa inuu horta isha ku yaal si loo arko, si sawirku u noqdo mid toosan oo casri ah.

Waa la garanayaa :

Masaafada shayga (yada) = 25 cm

Masaafada sawirka (yada) = -50 cm (taban sababtoo ah waa mid casri ah)

La weydiiyay : Dhererka diiradda (f) ee muraayadaha iyo awoodda muraayadda (P)

Jawab :

1/f = 1/s + 1/s'

1/f = 1/25 + 1/-50

1/f = 2/50 – 1/50

1/f = 1/50

f = 50/1 = 50 cm = 0,5 mitir

Dhererka diiradda togan macnaheedu waa in muraayadda la isticmaalay ay tahay muraayad wareegsan.

P = 1/f = 1/0,5 = +2 Diopters

Xoogga ama awoodda muraayadda waa +2 D. Calaamadda togan waxay ka dhigan tahay in muraayadda la isticmaalay ay tahay muraayad qaloocan.

Dhererka diiradda ee muraayadda ujeeddada (f)_ob) = 0,9 cm = 9 mm

Dhererka diiradda ee muraayadda indhaha (f)_ok) = 5 cm = 50 mm

Masaafada shayga u jiro muraayadda ujeeddada (s)_ob) = 10 mm

Dhererka shayga (h) = 0,5 mm

Barta u dhow isha caadiga ah (N) = 25 cm = 250 mm

Jawaab:

U fiirsasho la'aan la'aantu waxay la mid tahay u fiirsasho leh hoy yar, halkaas oo ishu ay nasato marka la daawanayo sawir aan dhammaad lahayn.

Marka hore, xisaabi masaafada sawirka laga bilaabo muraayadda ujeeddada. Muraayadda ujeeddada leh waa muraayad wareegsan, sidaa darteed qaacidada muraayadda toosan ayaa loo isticmaalaa:

1 / s_ob' = 1/f_ob – 1/s_ob = 1/9 – 1/10 = 10/90 – 9/90 = 1/90

s_ob' = 90/1 = 90 mm

Wadarta weyneynta mikroskoobka marka isha ay ku habboon tahay ugu yaraan ama marka sawirku uusan xad lahayn waxaa lagu xisaabiyaa qaacidada:

La weydiiyay: Wadarta weyneynta mikroskoobka (M)

Jawaab:

Ishu si yar ayay u qaabaysan tahay marka sawirku aad uga fog yahay, sida ka muuqata sawirka dhinaca.

Qaacidada weyneynta guud ee mikroskoobka marka isha ay ugu yaraan ku habboon tahay:

Macluumaadka:

M = weynaynta guud

l = dhererka mikroskoobka = masaafada u dhaxaysa muraayadda ujeeddada leh iyo muraayadda indhaha = dhererka diiradda ee muraayadda indhaha + masaafada sawirka u dhexeeya muraayadda ujeeddada leh (yada)_ob') = f_ok + s_ob'

Masaafada sawirka laga bilaabo muraayadda ujeeddada (s)_ob') :

1/f_ob = 1/s_ob + 1/s_ob'

1 / s_ob' = 1/f_ob – 1/s_ob = 1/2 – 1/2,2 = 2,2/4,4 – 2/4,4 = 0,2/4,4

Jawaab:

Fiiri sawirka kore. Marka isha ay ugu yaraan ku habboon tahay, sawirka ugu dambeeya ee ay samaysay muraayadda indhaha waa mid aan dhammaad lahayn. Si sawirka ugu dambeeya ee ay soo saarto muraayadda indhaha uu u noqdo mid aan dhammaad lahayn, sawirka dhabta ah ee ay soo saarto muraayadda indhaha waa inuu ahaadaa barta dhexe ee muraayadda indhaha. Sidaa darteed, masaafada u dhaxaysa muraayadda indhaha iyo muraayadda indhaha (l) = masaafada sawirka dhabta ah ee ka fog muraayadda indhaha (s)_ob') + dhererka diiradda ee muraayadda indhaha (f)_ok).

Masaafada sawirka dhabta ah laga bilaabo muraayadda ujeeddada (s)_ob') :
1 / s_ob + 1/s_ob' = 1/f_ob
1 / s_ob' = 1/f_ob – 1/s_ob
1 / s_ob' = 1/1,8 – 1/2
1 / s_ob' = 10/18 – 9/18 = 1/18
s_ob' = 18 cm

Masaafada u dhaxaysa muraayadda indhaha iyo muraayadda indhaha (dhererka tuubada mikroskoobka):
l = s_ob'+ f_ok
l = 18 cm + 6 cm
l = 24 cm

f₂ = 0,02439024 mitir
Xoogga muraayadda indhaha:
