He aha ka ʻokoʻa ma waena o IR a me RF?

Hoʻopau ʻia ka Infrared me IR. He ʻano ia o ka pāhawewe electromagnetic me nā lōʻihi nalu i ʻoi aku ka lōʻihi ma mua o ka mālamalama ʻike ʻia akā ʻoi aku ka pōkole ma mua o nā hawewe lekiō. Hoʻohana pinepine ʻia no ke kamaʻilio uea ʻole no ka mea hiki ke hāʻawi maʻalahi a loaʻa nā hōʻailona infrared me ka hoʻohana ʻana i nā diodes IR. No ka laʻana, hoʻohana nui ʻia ka infrared (IR) no ka mana mamao o nā mea uila e like me ke kīwī a me nā mea pāʻani DVD. Hiki ke hoʻohana ʻia no ka hoʻomehana ʻana, ka hoʻomaloʻo, ka ʻike ʻana, a me ka spectroscopy, a me nā mea ʻē aʻe.

Hoʻopau ʻia ka Radio Frequency me RF. E pili ana i ka laulā o nā alapine electromagnetic i hoʻohana maʻamau no ke kamaʻilio uea. Hoʻopili kēia i nā alapine mai 3 kHz a i 300 GHz. Ma ka hoʻololi ʻana i ke alapine, amplitude, a me ka pae o ka nalu lawe, hiki i nā hōʻailona RF ke lawe i ka ʻike ma nā wahi mamao loa. Nui nā noi e hoʻohana i ka ʻenehana RF, me ke kelepona, ka hoʻolaha, nā ʻōnaehana radar, nā kamaʻilio satellite, a me ka ʻupena pūnaewele. ʻO nā mea hoʻolele lekiō a me nā mea hoʻokipa, nā mea hoʻokele WiFi, nā kelepona paʻalima, a me nā hāmeʻa GPS he mau laʻana o nā lako RF.

Hoʻohana nui ʻia ʻo IR (Infrared) a me RF (Radio Frequency) no ke kamaʻilio uila, akā aia kekahi mau ʻokoʻa nui:
1. Laulā: He ʻoi aku ka nui o ka RF ma mua o ka infrared. Hiki i nā hoʻouna RF ke hele i nā paia, ʻoiai ʻaʻole hiki i nā hōʻailona infrared.
2. Laina ʻike: Pono nā hoʻouna ʻana i ka infrared i kahi laina ʻike ma waena o ka mea hoʻouna a me ka mea hoʻokipa, akā hiki ke kahe nā hōʻailona lekiō ma o nā keakea.
3. Hoʻopilikia: Hiki ke hoʻopili ʻia mai nā mea uila ʻē aʻe ma ka ʻāina i nā hōʻailona RF, ʻoiai he mea maʻamau ka hoʻopili ʻana mai nā hōʻailona IR.
4. Bandwidth: No ka mea he nui ka bandwidth o RF ma mua o IR, hiki iā ia ke lawe i nā ʻikepili hou aʻe i ka wikiwiki.
5. Ka hoʻohana ʻana i ka mana: No ka mea ʻoi aku ka liʻiliʻi o ka mana o IR ma mua o RF, ʻoi aku ka maikaʻi o nā mea lawe lima e like me nā mana mamao.

ʻO ka hōʻuluʻulu manaʻo, ʻoi aku ka maikaʻi o IR no ke kamaʻilio pōkole, ʻoi aku ka ʻike, ʻoiai ʻoi aku ka maikaʻi o RF no ka lōʻihi lōʻihi, ke kamaʻilio ʻana i nā pilikia.

Kāhea iā mā˚oua hiki iā mākou ke kaʻana like i ka ʻike hou aku e pili ana i nā kukui LED strip.
