Materesikopu ezvishandiso zveoptical - matambudziko nemhinduro

1. Kureba kwelenzi yemaziso ndeye 400 cm uye kureba kwelenzi yemaziso ndeye 20 cm. Kana ziso rakasununguka , sarudza:

a) Kukura kwese kweteresikopu (M)

b) daro remufananidzo kubva kune lenzi ine chinangwa ( d _ob '),

c) _daro remufananidzo kubva pane lenzi yemaziso ( doc ₎

d) daro riri pakati pemagirazi

Zvinozivikanwa:

Kureba kwe lenzi yekutarisa (f _ob ) = 400 cm

Kureba kwelenzi yemaziso ( foc ₎ = 20 _cm

Ziso rinozorora kuitira kuti mufananidzo chaiwo unogadzirwa ne lenzi iri panzvimbo yakatarisana ne lenzi iri panzvimbo yakatarisana ne lenzi iri uye nzvimbo yekutanga yakatarisana ne lenzi yemaziso.

Solution:

a) Kukura kwese (M)

M = f _ob / _{fo c}

M = 400 cm / 20 cm = 20 X

Mufananidzo wacho uri wepakombiyuta uye wakapindurwa.

b) Chinhambwe chemufananidzo kubva kune lenzi chaiyo ( d _ob ')

Kana ziso rakasununguka, daro remufananidzo kubva kune lenzi chaiyo ( d _ob ') = kureba kwelenzi chaiyo ( f _ob ) = 400 cm = 4 m.

c) Kureba kwemufananidzo chaiwo kubva pane lenzi _yemaziso ( doc ₎

Kana ziso rakasununguka, daro remufananidzo chaiwo nelenzi yemaziso (s _{o c} ) = kureba kwefocal lenzi yemaziso (f _oc ) = 20 cm = 0.2 m.

d) Kureba pakati pemagirazi

Kureba pakati pemalenzi = kureba kweteresikopu (l) = kureba kwefocal yelenzi inoonekwa (f _ob ) + kureba kwefocal yelenzi yemaziso (f _oc ) = 400 cm + 20 cm = 420 cm.

2. Kureba pakati pe lenzi yemaziso ne lenzi yemaziso i20 cm . Kukura kwese kweteresikopu kana ziso rakasununguka i40X. Verenga urefu hwe focal lenzi yemaziso (fo _{c )} uye urefu hwe focal lenzi yemaziso (f _ob )

Zvinozivikanwa:

kureba kweteresikopu (l) = 20 cm

kukura kwese kweteresikopu (M) = 40

Solution:

Kana ziso rakasununguka, kureba kwelenzi yemaziso (f _oc ) + kureba kwelenzi yekutarisa (f _ob ) = kureba kweteresikopu (l)

fo _{o c} + f _ob = l

f _ob = l – _{fo c}

f _ob = 20 – fo _{c —–} > equation 1

Kukura kwese kweteresikopu (M):

M = f _ob / _{fo c}

f _ob = M _{fo c}

f _ob = 40 fo _{c —–} > equation 2

Kureba kwelenzi yemaziso :

Isa f _ob muequation 1 na f _ob muequation 2:

f _ob = 20 – _{fo c}

40 fo _{c =} 20 – _{fo c}

40 fo _{c +} fo _{c =} 20

41 fo _{c =} 20

fo _{c =} 20 cm / 41

fo _{c =} 0.5 cm

Kureba kwelenzi yemaziso = 0.5 cm.

Kureba kwelenzi yekutarisa :

f _ob = 20 – f _oc

f _ob = 20 – 0.5

f _ob = 19.5 cm
