A. Hiki ke wehewehe ʻia ka hopena photoelectric ma ka noʻonoʻo ʻana i ka mālamalama ma ke ʻano he ʻāpana, ʻaʻole ma ke ʻano he nalu. ʻAʻole hoʻolaha mau ʻia ka ikehu mālamalama i ka neʻe ʻana o nā nalu akā he mau ʻeke liʻiliʻi i kapa ʻia ʻo photons aka light quanta (e noʻonoʻo wale iā ia e like me ka wai ua).
B. Inā piʻi ke alapine (frequency) o ke kukui a laila piʻi nā electrons e puka mai ana mai ka ʻili metala. Ke piʻi ke alapine (frequency) o ke kukui , piʻi ka ikehu o ke kukui. ʻO ka nui o ka ikehu e omo ai, ʻoi aku ka nui o nā electrons e puka mai ana mai ka ʻili metala.
C. ʻO ka ikaika o ke kukui e pili ana i ka wikiwiki o ka hoʻokuʻu ʻana o ka ikehu a i ʻole ka wikiwiki o ka ikehu kukui ma luna o ka ʻili metala. ʻO ka ikaika o ke kukui i hoʻonui ʻia ʻaʻole ia he manaʻo ua hoʻonui ʻia ka ikehu o ke kukui. Aia ka ikehu photon (E = hf) i ke alapine (f) a i ʻole ka nalu a me ke kūpaʻa o Planck (h).
D. Hana ka hopena photoelectric ma ke alapine (frequency) a i ʻole ka nalu o ke kukui ultraviolet ʻo ia hoʻi nā kukuna ultraviolet. ʻO ke alapine (frequency) ultraviolet ka paepae alapine (frequency) kahi e hiki ai i ka ikehu photon ke hoʻokuʻu i nā electrons mai ka ʻili metala. ʻAʻole hiki ke alapine (frequency) infrared no ka mea he liʻiliʻi loa ia, inā ʻaʻole, hiki ke alapine (frequency) o nā kukuna x a me nā kukuna gamma ma muli o ke alapine (frequency) ʻoi aku ma mua o ka ultraviolet.
ʻAʻole pili ka ikaika o ke kukui i ka hopena photoelectric
ʻO C ka pane pololei.
