Magirazi akasiyana-siyana - matambudziko nemhinduro

1. Chinhu chakareba masendimita mashanu chinoiswa 15 cm kubva pane lenzi ine urefu hwemasentimita makumi matatu . Sarudza daro remufananidzo , kukura kwemufananidzo, kukwirira kwemufananidzo, uye hunhu hwemufananidzo.

Zvinozivikanwa:

Kureba kwefocal (f) = -30 cm

Chiratidzo che "minus" chinoratidza kuti nzvimbo iri pamberi pechinhu iri pakombiyuta kana kuti mwaranzi haipfuuri nepanzvimbo yacho.

Kureba kwechinhu (h _o ) = 5 cm

Daro rechinhu (do _o ) = 15 cm

Zvinodiwa: Kureba kwemufananidzo (d _i ), kukura kwemufananidzo (m), kukwirira kwemufananidzo (h _i ) uye hunhu hwemufananidzo.

Solution:

Kuumbwa kwemufananidzo ne lenzi yakasiyana-siyana:

Kureba kwemufananidzo (di _i ):

1/d _i = 1/f – 1/d _o = -1/30 – 1/15 = -1/30 – 2/30 = -3/30

d _i = -30/3 = -10 cm

Chiratidzo che "minus" chinoratidza kuti mufananidzo wacho uri wepakombiyuta kana kuti mwaranzi haipfuuri nepamufananidzo.

Kukura kwemufananidzo (m):

m = – di _i / do _o = -(-10)/15 = 10/15 = 2/3

Chiratidzo chekuwedzera chinoratidza kuti mufananidzo wacho wakamira.

Mufananidzo wacho mudiki ne 2/3 pane chinhu chacho.

Kureba kwemufananidzo (h _i ):

m = h _i / h _o

h _i = mh _o = (2/3)5 = 10/3 = 3.3 cm

Chiratidzo chekuwedzera chinoratidza kuti mufananidzo wacho wakamira.

Hunhu hwemufananidzo:

Hunhu hwemufananidzo hunoumbwa negirazi rinopatsanurana:

- pamhepo

- yakatwasuka

- mufananidzo mudiki pane chinhu chacho

- daro remufananidzo diki pane daro rechinhu

2. Chinhu chakareba masendimita gumi chinoiswa 60 cm kubva pane lenzi ine urefu hwemasendimita makumi matatu. Sarudza daro remufananidzo, kukura kwemufananidzo, kukwirira kwemufananidzo, uye hunhu hwemufananidzo.

Zvinozivikanwa:

Kureba kwefocal (f) = -30 cm

Chiratidzo che "minus" chinoratidza kuti nzvimbo iri pamberi pechinhu iri pakombiyuta kana kuti mwaranzi haipfuuri nepanzvimbo yacho.

Kureba kwechinhu (h) = 10 cm

Daro rechinhu (do _o ) = 60 cm

Zvinodiwa: Daro remufananidzo (d _i ), kukura kwemufananidzo (m), kukwirira kwemufananidzo (h _i ) uye hunhu hwemufananidzo

Solution:

Kuumbwa kwemufananidzo ne lenzi yakasiyana-siyana:

Kureba kwemufananidzo (di _i ):

1/d _i = 1/f – 1/d _o = -1/30 – 1/60 = -2/60 – 1/60 = -3/60

d _i = -60/3 = -20 cm

Chiratidzo che "minus" chinoratidza kuti mufananidzo wacho uri wepakombiyuta kana kuti mwaranzi haipfuuri nepamufananidzo.

Kukura kwemufananidzo (m):

m = -d _i /do _o = -(-20)/60 = 20/60 = 1/3

Chiratidzo chekuwedzera chinoratidza kuti mufananidzo wacho wakamira.

Mufananidzo wacho mudiki ne 1/3 pane chinhu chacho.

Kureba kwemufananidzo (h _i ):

m = h _i / h _o

h _i = mh _o = (1/3)10 = 10/3 = 3.3 cm

Chiratidzo chekuwedzera chinoratidza kuti mufananidzo wacho wakamira.

Zvimiro zvemufananidzo

- zviri paindaneti nekuti mwaranzi haipfuure nepamufananidzo

- yakatwasuka

- mufananidzo mudiki pane chinhu chacho

- daro remufananidzo diki pane daro rechinhu
