Materesikopu ezvishandiso zveoptical - matambudziko nemhinduro

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

a) Kukura kwese kwe telescope (M)

b) chinhambwe chemufananidzo kubva kune lenzi ine chinangwa (d_ob'),

c) chinhambwe chemufananidzo kubva kune lenzi yemaziso (d_oc)

d) daro riri pakati pe lenses

Zvinozivikanwa:

Kureba kwe lenzi yechinangwa (f_ob) = 400 cm

Kureba kwegirazi remaziso (f_oc) = 20 cm

Ziso rakasununguka kuitira kuti Mufananidzo chaiwo unogadzirwa ne lenzi yekutarisa uri panzvimbo ye lenzi yekutarisa uye panzvimbo yekutanga ye lenzi yekuona.

Solution:

a) Kukura kwese (M)

M = f_ob /f_oc

M = 400 cm / 20 cm = 20X

Mufananidzo wacho uri wepakombiyuta uye wakapindurwa.

b) Kureba kwemufananidzo kubva kune lenzi ine chinangwa (d_ob')

Kana ziso rakasununguka, mufananidzo uri kure ne lenzi chaiyo (d_ob') = kureba kwegirazi rekutarisa (f_ob) = 400 cm = 4 m.

c) Kureba kwemufananidzo chaiwo kubva pane lenzi yemaziso (d_oc)

Kana ziso rakasununguka, daro remufananidzo chaiwo nelenzi yemaziso rinoonekwa. (s_oc) = kureba kwegirazi remaziso (f_oc) = 20 cm = 0.2 m.

d) Kureba pakati pemagirazi

Kureba pakati pemagirazi = kureba kweteresikopu (l) = kureba kwegirazi rekutarisa (f_ob+ kureba kwegirazi remaziso (f_oc) = 400 cm + 20 cm = 420 cm.

2. The mufambo pakati pe lenzi chaiyo ne lenzi yemaziso pane 20 cm. Kukura kweteresikopu kana ziso rakasununguka kunosvika 40X. Verenga urefu hwelenzi yemaziso. (f_oc) uye kureba kwe lenzi yekutarisa (f_ob)

Zvinozivikanwa:

kureba kweteresikopu (l) = 20 cm

kukura kwese kwemateresikopu (M) = 40X

Solution:

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

f_oc +f_ob = l

f_ob = l – f_oc

f_ob = 20 – f_oc —–> equation 1

Kukura kwese kwematelesikopu (M):

M = f_ob /f_oc

f_ob = M f_oc

f_ob = 40 f_oc —–> equation 2

Kureba kwelenzi yemaziso :

Chinotsiva f_ob muequation 1 ne f_ob muequation 2:

f_ob = 20 – f_oc

40 f_oc = 20 – f_oc

40 f_oc +f_oc = 20

41 f_oc = 20

f_oc = 20 cm / 41

f_oc = 0.5 masendimita

Kureba kwelenzi yemaziso = 0.5 cm.

Kureba kwe lenzi yechinangwa :

f_ob = 20 – f_oc

f_ob = 20 - 0.5

f_ob = 19.5 masendimita
