A. Ana iya bayyana tasirin hasken lantarki ta hanyar la'akari da haske a matsayin barbashi, ba a matsayin raƙuman ruwa ba. Ƙarfin haske ba ya rarrabuwa akai-akai yayin da raƙuman ruwa ke motsawa amma ƙananan fakiti ne da ake kira photons wanda aka fi sani da light quanta (kawai ka yi tunanin kamar ruwan sama).
B. Idan yawan haske ya ƙaru , to electrons da ke fitowa daga saman ƙarfe yana ƙaruwa. Lokacin da yawan haske ya ƙaru, makamashin haske yana ƙaruwa. Girman kuzarin yana ɗaukar ƙarin electrons da ke fitowa daga saman ƙarfe.
C. Ƙarfin haske ya yi daidai da saurin fitar da kuzari ko saurin kuzarin haske a saman ƙarfe. Ƙarfin haske da aka faɗaɗa ba yana nufin cewa ƙarfin haske ya ƙaru ba. Ƙarfin photon (E = hf) ya dogara da mita (f) ko tsawon rai da kuma daidaiton Planck (h).
D. Tasirin hasken rana yana faruwa ne a mita ko tsawon hasken ultraviolet wanda aka fi sani da hasken ultraviolet. Mitar ultraviolet ita ce mitar bakin da makamashin photon ke iya sakin electrons daga saman ƙarfe. Mitar infrared ba za ta iya zama ba saboda ƙanƙanta ce, in ba haka ba, mitar x-ray da haskoki na gamma na iya zama saboda yawan mita fiye da hasken ultraviolet.
E. Ƙarfin hasken ba ya shafar tasirin hasken lantarki
Amsar da ta dace ita ce C.

Bayani (1): Wannan magana gaskiya ce. Idan tsawon da ke zuwa ya fi ƙanƙanta fiye da tsawon iyakar ƙarfe to ba a fitar da electrons ba.
Bayani (2): Wannan magana gaskiya ce. Fitowar electrons daga saman ƙarfe ya dogara ne akan mita ko tsawon rai ko kuzarin haske.
Bayani (3): Wannan magana ƙarya ce. Electrons suna fitowa daga ƙarfe idan mitar haske ta fi mitar ƙofar ƙarfe girma. Rashin electrons daga saman ƙarfe ya dogara ne akan kuzarin haske maimakon ƙarfin haske. Ƙarfin haske ya dogara ne akan mita ko tsawon rai (E = hf). Ƙarfin haske yana da alaƙa da saurin fitar da kuzarin haske.

Bayani (1): Wannan magana gaskiya ce. Raƙuman lantarki sun ƙunshi nau'ikan raƙuman lantarki da yawa waɗanda ke da mitoci ko tsayi daban-daban. Raƙuman lantarki ne kawai waɗanda ke da mita ko tsayi fiye da tsayin ko tsayin daka za su iya cire electrons daga ƙarfe.
Bayani (2): Wannan magana gaskiya ce. Idan mitar haske ta fi ta ƙarfe ƙanƙanta, to za a iya raba wutar lantarki da ƙarfe. Akasin haka, idan mitar haske ta fi ta ƙarfe girma, za a saki wutar lantarki daga ƙarfe.
Bayani (3): Wannan magana ƙarya ce. Aikin aikin ƙarfe shine mafi ƙarancin aiki ko mafi ƙarancin kuzari da ake buƙata don cire electrons daga saman ƙarfe. Aikin aikin kowane ƙarfe ya dogara da halayen ƙarfe.
