Hiki ke wehewehe ʻia ka mālamalama ma nā ʻano he nui.
He photon, he ʻano nalu, he ʻāpana, he alapine electromagnetic. Hana ʻia ka mālamalama ma ke ʻano he ʻāpana kino a me ka nalu.
ʻO ka mea a mākou e noʻonoʻo ai he māmā kahi ʻāpana liʻiliʻi o ka spectrum electromagnetic i ʻike ʻia he kukui ʻike kanaka, kahi e maʻalahi ai nā cell i nā maka kanaka. Hoʻopili ka nui o nā maka holoholona i kahi laulā like.
Hiki i nā ʻōpala, nā manu, a me nā pōpoki a me nā ʻīlio ke ʻike i ke kukui UV, a ʻo kekahi mau holoholona ʻē aʻe e ʻike i ka infrared; nā iʻa, nā nahesa, a me nā makika!
Na ka lolo mammalian e wehewehe/wehewehe i ka malamalama i 'kala'. ʻO ka lōʻihi o ka nalu a i ʻole ke alapine o ka mālamalama ka mea e hoʻoholo ai i ko mākou kala i ʻike ʻia. He ʻulaʻula ke ʻano o ka nalu lōʻihi a ʻo ka lōʻihi hawewe pōkole he uliuli.
No laila, ʻaʻole pili ka kala i ke ao holoʻokoʻa, akā he mea i hana ʻia i ko mākou manaʻo. E hōʻike wale ana i kahi hapa liʻiliʻi o ka spectrum electromagnetic piha. He kiʻi kiʻi wale nō ma kahi alapine.
ʻO ke ʻano kumu o ka mālamalama he kahawai o nā kiʻi, oscillating ma kahi hawewe kikoʻī.
