Nā ʻano o nā nalu - nā pilikia a me nā hoʻonā
1. Penei nā ʻano laulā o ka nalu :
(1) ʻaʻole hiki ke hoʻolaha i loko o kahi hakahaka
(2) e neʻe pololei ana i kahi ʻano like ʻole
(3) ke ʻike nei i ka noʻonoʻo ʻana
(4) ke ʻike nei i ka diffraction
(5) ʻike i ke komo ʻana
Mai nā ʻano nalu i luna , e pili ana i nā ʻano o nā nalu māmā…

( 1) He nalu electromagnetic ka nalu māmā ʻaʻole pono i kahi mea hoʻolaha. No ka mea, ʻaʻole pono ia i kahi mea hoʻolaha, hiki i nā nalu electromagnetic ke hoʻolaha i loko o kahi hakahaka.
(2) Ke komo nā nalu māmā e holo ana i loko o kahi waena i kahi waena hou, ua hoʻohuli ʻia nā nalu māmā. ʻO ka refraction ke kuhikuhi o ka laha ʻana o ka nalu māmā. Hana ʻia ka refraction ma muli o nā ʻokoʻa o ka wikiwiki o nā nalu māmā i kēlā me kēia waena like ʻole.
(3) Ma waho aʻe o ka hoʻohuli ʻia ʻana, ua hōʻike ʻia nā nalu māmā. ʻO ka hōʻike ʻana o ke kukui e kahi aniani pālahalaha kekahi laʻana o ka hōʻike ʻana o ke kukui
( 4) ʻAʻole ʻike wale ʻia ka diffraction e nā nalu electromagnetic e like me nā nalu māmā akā ʻike ʻia hoʻi e nā nalu mechanical e like me nā nalu wai a me nā nalu kani.
( 5) Ma waho aʻe o ka ʻike ʻia e nā nalu electromagnetic e like me nā nalu māmā, ʻike ʻia hoʻi ka hoʻopilikia ʻia e nā nalu mechanical e like me nā nalu wai, nā nalu kaula a i ʻole nā nalu kani.
ʻAʻole maopopo
2. E nānā i nā ʻano nalu ma lalo nei!
(1) ke ʻike nei i ka diffraction
(2) ke ʻike nei i ka noʻonoʻo ʻana
(3) ʻaʻole hiki ke hoʻolaha i loko o kahi hakahaka
(4) hiki ke ʻike i ka polarization
(5) e neʻe pololei ana i ka wā e hele ana ma waena o ʻelua mau media like ʻole
Mai nā ʻano nalu i luna e pili ana i nā ʻano o nā nalu kani…

( 1) ʻAʻole ʻike wale ʻia ka diffraction e nā nalu electromagnetic e like me nā nalu māmā, akā, e nā nalu mechanical e like me nā nalu kani.
(2) ʻIke ʻia ka noʻonoʻo ʻana a i ʻole ka noʻonoʻo ʻana e nā nalu electromagnetic e like me nā nalu māmā a me nā nalu mechanical e like me nā nalu kani a i ʻole nā nalu wai. ʻO kahi laʻana o kahi hanana noʻonoʻo o nā nalu kani he echo.
(3) He mau nalu kani nā nalu mechanical. He mau nalu mechanical nā nalu e pono ai kahi mea hoʻolaha i mea e hoʻolaha ai. Inā ʻaʻohe mea like i loko o kahi hakahaka a laila ʻaʻole hiki i nā nalu kani ke hoʻolaha.
(4) ʻIke ʻia ka polarization e nā nalu transverse e like me nā nalu kaula, nā nalu ʻili a me nā nalu electromagnetic e like me nā nalu māmā. He mau nalu longitudinal nā nalu kani a no laila ʻaʻole hiki ke ʻike i ka polarization.
(5) Ke hele nei mai kahi waena i kahi waena ʻē aʻe, huli a hoʻokaʻawale paha nā nalu kani i ke kuhikuhi o ka hoʻolaha ʻana. Hana ʻia ka refraction ke hoʻomaka nā nalu e komo i kahi waena ʻē aʻe.
ʻAʻole maopopo
3. E nānā i ka ʻōlelo aʻe!
(1) hiki ke hōʻike ʻia
(2) hiki ke hōʻike ʻia
(3) hiki ke hoʻokaʻawale ʻia
(4) koi i ka waena
(5) he nalu lōʻihi
ʻO nā ʻano o nā nalu māmā...
A. (1), (2), a me (3)
B. (1), (3), a me (4)
C. (1), (4), a me (5)
D. (2), (3, a me (4)
E. (3), (4), a me (5)

ʻO nā nalu māmā e komo pū ana me nā nalu electromagnetic e hoʻolaha me ka ʻole o kahi medium a me kahi nalu transverse.
