Teleskoobyada qalabka indhaha - dhibaatooyinka iyo xalalka

1. Dhererka diiradda ee muraayadda ujeeddada leh waa 400 cm, dhererka diiradda ee muraayadda indhahana waa 20 cm. Haddii isha ay dabacsan tahay, go'aami:

a) Ballaarinta guud ee teleskoobka (M)

b) masaafada sawirka laga soo bilaabo muraayadda ujeeddada ( d _ob '),

c) masaafada sawirka laga soo bilaabo muraayadda indhaha ( d _{o c} )

d) masaafada u dhaxaysa muraayadaha indhaha

La yaqaan:

Dhererka diiradda ee muraayadda ujeeddada (f _ob ) = 400 cm

Dhererka diiradda ee muraayadda indhaha ( foc ₎ = 20 _cm

Ishu waa dabacsan tahay si sawirka dhabta ah ee uu soo saaro muraayadda ujeeddada leh uu ugu jiro barta dhexe ee muraayadda ujeeddada leh iyo barta hore ee isha indhaha.

Xalka:

a) Ballaarinta guud (M)

M = f _ob / f _{o c}

M = 400 cm / 20 cm = 20 X

Sawirku waa mid casri ah oo rogrogmi kara.

b) Masaafada sawirka laga bilaabo muraayadda ujeeddada ( d _ob ')

Haddii isha la dejiyo, masaafada sawirka ee muraayadda ujeeddada leh ( d _ob ') = dhererka diiradda ee muraayadda ujeeddada leh ( f _ob ) = 400 cm = 4 m.

c) Masaafada sawirka dhabta ah laga bilaabo muraayadda indhaha ( d _{o c} )

Haddii isha la dejiyo, masaafada sawirka dhabta ah iyo muraayadda indhaha ( _{oc )} = dhererka diiradda ee muraayadda indhaha (f _oc ) = 20 cm = 0.2 m.

d) Masaafada u dhaxaysa muraayadaha indhaha

Masaafada u dhaxaysa muraayadaha = dhererka teleskoobka (l) = dhererka diiradda muraayadda ujeeddada (f _ob ) + dhererka diiradda muraayadda indhaha (f _oc ) = 400 cm + 20 cm = 420 cm.

2. Masaafada u dhaxaysa muraayadda indhaha iyo muraayadda indhaha waa 20 cm . Weyneynta guud ee teleskoobka marka isha la nasto waa 40X. Xisaabi dhererka diiradda ee muraayadda indhaha (f _{o c} ) iyo dhererka diiradda ee muraayadda indhaha (f _ob )

La yaqaan:

Dhererka teleskoobka (l) = 20 cm

weyneynta guud ee teleskoobka (M) = 40

Xalka:

Haddii isha la dejiyo, dhererka diiradda ee muraayadda indhaha (f _oc ) + dhererka diiradda ee muraayadda ujeeddada (f _ob ) = dhererka teleskoobka (l)

f _{o c} + f _ob = l

f _ob = l – f _{o c}

f _ob = 20 – f _{o c} —–> isla'egta 1

Ballaarinta guud ee teleskoobka (M):

M = f _ob / f _{o c}

f _ob = M f _{o c}

f _ob = 40 f _{o c} —–> isla'egta 2

Dhererka diiradda ee muraayadda indhaha :

Ku beddel f _ob ee isla'egta 1 iyo f _ob ee isla'egta 2:

f _ob = 20 – f _{o c}

40 f _{o c} = 20 – f _{o c}

40 f _{o c} + f _{o c} = 20

41 f _{o c} = 20

f _{o c} = 20 cm / 41

f _{o c} = 0.5 cm

Dhererka diiradda ee muraayadda indhaha = 0.5 cm.

Dhererka diiradda ee muraayadda ujeeddada :

f _ob = 20 – f _oc

f _ob = 20 – 0.5

f _ob = 19.5 cm
