A. Mhedzisiro yemagetsi inogona kutsanangurwa nekufunga nezvechiedza sechinhu chidiki, kwete semafungu. Simba rechiedza harigoverwe nguva dzose sezvo mafungu achifamba asi mapaketi madiki anonzi maphoton aka light quanta (ingofungidzira semvura yemvura).
B. Kana kuwanda kwechiedza kuwedzera ipapo maerekitironi anobuda pamusoro pesimbi anowedzera. Kana frequency yechiedza kuwedzera Simba rechiedza rinowedzera. Simba guru rinotora maerekitironi akawanda kubva pamusoro pesimbi.
C. Kusimba kwechiedza kunoenderana nekumhanya kwekubuda kwesimba kana kukurumidza kwesimba rechiedza pamusoro pesimbi. Kusimba kwe chiedza Kukura hazvirevi kuti simba rechiedza rakura. Simba re photon (E = hf) rinoenderana ne frequency (f) kana wavelength uye Planck's constant (h).
D. Mhedzisiro yemagetsi inoitika pahuwandu kana wavelength yechiedza che ultraviolet chinonzi ultraviolet rays. Ma frequency e ultraviolet ihuwandu hwe threshold iyo simba re photon rinokwanisa kuburitsa ma electron kubva pamusoro pesimbi. Ma frequency e infrared haagone kuve nekuti idiki zvakanyanya, zvikasadaro, ma frequency e x-rays ne gamma rays anogona kunge ari nekuda kwehuwandu hwakawanda kupfuura ultraviolet.
E. Kusimba kwechiedza hakukanganisi mhedzisiro ye photoelectrict

(1) Mhedzisiro yemagetsi inogona kutsanangurwa nekufungidzira kuti chiedza chine mapaketi esimba
(2) Kushanda kwemagetsi emagetsi kunogona kuratidza kuti chiedza chinogona kuita sechiedza wave
(3) Simba remaerekitironi rinobuda pamusoro pesimbi rinoenderana nehuwandu hwemaerekitironi
(4) Mhedzisiro yemagetsi inoitika pedyo nenzvimbo ye infrared

(1) Kuparadzaniswa kwemaerekitironi kubva musimbi kunotsanangurwa nehukuru hwemwenje unouya
(2) Kusimba kwechiedza chiri kuuya hakuvimbisi kubviswa kwemaerekitironi kubva pamusoro pesimbi
(3) Pasi pehuwandu hwemagetsi, maerekitironi anoramba ari kunze kwesimbi sezvo simba rechiedza chinouya richikura.
Chirevo chakarurama chine chekuita nemhedzisiro ye photoelectric ndechekuti…..

Chirevo (1): Chirevo ichi ndechechokwadi. Kana urefu hwemafungu hunouya huri hudiki pane urefu hwemafungu esimbi, maerekitironi haaburitswe.
Chirevo (2): Chirevo ichi ndechechokwadi. Kubuda kwemaerekitironi kubva pamusoro pesimbi kunoenderana nefrequency kana wavelength kana simba rechiedza.
Chirevo (3): Chirevo ichi ndechenhema. Maerekitironi anobuda musimbi kana frequency yechiedza yakakura kupfuura frequency yesimbi. Kusavapo kwemaerekitironi kubva pamusoro pesimbi kunoenderana nesimba rechiedza kwete kusimba kwechiedza. Simba rechiedza rinoenderana frequency kana wavelength (E = hf). Kusimba kwechiedza kwakabatana nekumhanya kwesimba rechiedza rinoburitswa.

(1) Maerekitironi anogona kubuda pamusoro pesimbi kana simbi yapiswa nemafungu emagetsi
(2) Kubviswa kwemaerekitironi kubva pamusoro pesimbi kunoenderana nekuwanda kwechiedza chinouya
(3) Basa resimbi imwe neimwe rakafanana
Chirevo chakarurama chine chekuita nemhedzisiro ye photoelectric ndechekuti…..
mhinduro
Chirevo (1): Chirevo ichi ndechechokwadi. Mafungu emagetsi ane marudzi akawanda emafungu ane mafungu akasiyana kana marefu ewavelength. Mafungu emagetsi ane marefu kana wavelength akakura kupfuura threshold kana marefu ewavelength anogona kubvisa maerekitironi kubva musimbi.
Chirevo (2): Chirevo ichi ndechechokwadi. Kana frequency yechiedza iri diki pane frequency yesimbi, saka elektroni haiparadzaniswi nesimbi. Kusiyana neizvi, kana frequency yechiedza iri yakakura kupfuura frequency yesimbi, maerekitironi anoburitswa kubva musimbi.
Chirevo (3): Chirevo ichi ndechenhema. Basa rekushanda kwesimbi ndiro basa diki kana simba diki rinodiwa kubvisa maerekitironi pamusoro pesimbi. Basa rekushanda kwesimbi yega yega rinoenderana nehunhu hwesimbi.

(1) Maerekitironi anoburitswa mumhedzisiro ye photoelectric anonzi maerekitironi e photon
(2) Mwero wemaerekitironi anobuda hautsamiri pakusimba kwechiedza chine chekuita nesimbi
(3) Simba remagetsi remaerekitironi anoburitswa rinoenderana nesimba remafungu echiedza ari pamusoro pesimbi
(4) Kubvisa maerekitironi kubva pamusoro pesimbi isina muganhu (f)o)
Chirevo chechokwadi pamusoro pemhedzisiro ye photoelectric ndechekuti…..
mhinduro
(1) Maerekitironi anoburitswa nemwaranzi anonzi maerekitironi ezuva nezuva
(2) Mwero wemaerekitironi anoburitswa unoenderana nehuwandu kana huwandu hwemaerekitironi anoburitswa kwenguva yakati. Mwero wemaerekitironi anoburitswa unokanganiswa nekusimba kwechiedza, uko kusimba kwechiedza kwakabatana nekumhanya kwekufambiswa kwechiedza. Kusimba kwechiedza kunokanganisa chete kana simba rechiedza rakakura kupfuura simba remuganho wesimbi. Kana simba rechiedza riri diki pane simba remuganho wesimbi, kusimba kwechiedza hakuna zvakunobatsira.
(3) Chirevo ichi ndechechokwadi. Simba remagetsi rinobuda rinoenderana nesimba remafungu echiedza ari pamusoro pesimbi. Electron inoburitswa kubva pamusoro pesimbi chete kana simba rechiedza rakawanda kupfuura simba resimbi.
(4) Mashoko aya ndeenhema. Kana frequency yechiedza chinouya iri diki pane frequency yesimbi, maerekitironi haaburitswe. Saka kubuda kwemaerekitironi kunoenderana nefrequency yethreshold.

(1) kuwanda kwechiedza chinovhenekera cathode kunofanira kunge kwakakura kupfuura kuwanda kwechiedza
(2) basa re cathode yesimbi rakakura kupfuura simba rechiedza rinovhenekera cathode
(3) kureba kwechiedza kunofanira kunge kwakakura kupfuura kureba kwechiedza chinopenya pa cathode
(4) simba remagetsi remaerekitironi anoburitswa kubva mu cathode rinofanira kunge rakakura kupfuura simba remuganho
Kuti ma photoelectron akwanise kusangana:
mhinduro
(1) Chirevo ichi ndechechokwadi. Photoelectric inoitika kana frequency yechiedza chinovhenekera simbi ye cathode, yakakura kupfuura frequency ye threshold yesimbi ye cathode.
(2) Mashoko aya ndeenhema. Basa rekushanda ibasa diki kana simba diki rinodiwa kuti maerekitironi abudiswe. Kuti photoelectric iitike, simba rechiedza rinofanira kunge rakakura kupfuura basa resimbi cathode.
(3) Mashoko aya ndeenhema. Photoelectric inoitika kana wavelength yechiedza ichivhenekera cathode, yakakura kupfuura wavelength ye threshold ye cathode yesimbi.
(4) Chirevo ichi ndechechokwadi. Kuti tipukunyuke kubva musimbi, simba remagetsi remaerekitironi rinofanira kunge rakakura kupfuura simba remuganho wesimbi ye cathode.
Mhinduro dzakarurama ndi (1) na (4).

(1) Basa rekushanda kwesimbi rinofanira kunge riri shoma pane simba rechiedza rinovhenekera cathode yesimbi
(2) Simba remuganho we cathode rakakura kupfuura simba rechiedza rinovhenekera simbi ye cathode
(3) Simba remagetsi rinoburitswa kubva mu cathode rinogara rakakura kupfuura simba re cathode threshold
(4) Simba remagetsi rinoburitswa kubva pamusoro pe cathode rinoenderana nesimba rechiedza rinovhenekera cathode.
