Electromagnetic muaj kuab paug yog qhov tshwm sim ntawm kev loj hlob ntawm tib neeg kev vam meej, uas ua kev puas tsuaj rau ib puag ncig tag nrho. Kev ua qias tuaj ntawm hom no tau pib tshwm sim tom qab kev tsim tawm ntawm Nikola Tesla khoom siv ua haujlwm ntawm kev hloov tam sim no. Raws li qhov tshwm sim, ib puag ncig muaj kev cuam tshuam zoo rau cov cuab yeej hluav taws xob, TV thiab xov tooj cua, kab hluav taws xob, khoom siv thev naus laus zis, duab xoo hluav taws xob thiab teeb tsa laser, nrog rau lwm qhov chaw muaj kuab paug.
Kev txiav txim siab ntawm cov khoom siv hluav taws xob
Raws li qhov tshwm sim ntawm kev ua haujlwm ntawm cov chaw, ib qho hluav taws xob hluav taws xob tau tshwm sim. Nws yog tsim los ntawm kev sib cuam tshuam ntawm ntau daim teb thiab dipole lub cev nrog muaj hluav taws xob them. Raws li qhov tshwm sim, ntau vuag raug tsim hauv qhov chaw:
- xov tooj cua vuam;
- ultraviolet;
- infrared;
- ntxiv ntev;
- tawv;
- xoo hluav taws xob;
- terahertz;
- gamma;
- pom lub teeb.
Lub ntsuas hluav taws xob muaj qhov txawv ntawm hluav taws xob thiab kab hluav taws xob. Qhov farther los ntawm qhov chaw, qhov ntau attenuated hluav taws xob. Nyob rau hauv txhua kis, cov pa phem kis tau thoob ib cheeb tsam loj.
Qhov pib tshwm sim ntawm kev ua qias tuaj
Electromagnetic keeb kwm yav dhau los yeej ib txwm nyob hauv ntiaj chaw. Nws txhawb nqa kev txhim kho ntawm lub neej, tab sis, muaj lub ntuj hloov, tsis txhob ua mob ib puag ncig. Yog li, tib neeg tuaj yeem cuam tshuam nrog hluav taws xob hluav taws xob, siv cov pob zeb muaj nqi thiab pob zeb muaj nqi hauv lawv cov kev ua ub no.
Tom qab lub neej kev lag luam tau pib siv cov cuab yeej siv los ntawm hluav taws xob, thiab hauv lub neej txhua hnub - kev tsim hluav taws xob, kev siv hluav taws xob tau nce ntxiv. Qhov no coj mus rau qhov tshwm sim ntawm vuag ntawm xws ntev, uas tsis muaj nyob rau hauv qhov ua ntej. Raws li qhov tshwm sim, txhua yam khoom siv hluav taws xob uas khiav hluav taws xob yog qhov khoom siv hluav taws xob ua paug.
Nrog kev tshwm sim ntawm anthropogenic qhov chaw muaj kuab paug, electromagnetic teb tau pib muaj kev cuam tshuam tsis zoo rau tib neeg kev noj qab haus huv thiab ntawm kev xwm txheej. Qhov no yog li cas qhov tshwm sim ntawm electromagnetic smog tshwm sim. Nws tuaj yeem pom ob qho tib si hauv qhov chaw qhib, hauv thiab sab nraum lub nroog, thiab sab hauv tsev.
Kev cuam tshuam rau ib puag ncig
Cov pa hluav taws xob ua paug muaj kev hem thawj rau ib puag ncig, vim nws muaj kev cuam tshuam tsis zoo rau ib puag ncig. Ua li cas nws tshwm sim tiag tiag tsis paub tseeb, tab sis hluav taws xob cuam tshuam rau cov qauv ntawm daim nyias nyias ntawm cov kab mob ntawm cov muaj sia. Ua ntej tshaj plaws, dej yog paug, nws cov khoom hloov, thiab kev ua haujlwm tsis meej. Tsis tas li, hluav taws xob ua rau qis qis ntawm kev tsim dua tshiab ntawm cov nroj tsuag thiab cov tsiaj cov nqaij, ua rau txo qis kev ciaj sia thiab nce ntawm lub neej no. Ib qho ntxiv, hluav taws xob ntxiv pab txhawb kev sib hloov.
Raws li cov pa phem no ua rau hauv cov nroj tsuag, qhov ntau thiab tsawg ntawm cov qia, paj, txiv hmab txiv ntoo hloov, thiab lawv cov duab hloov. Hauv qee hom tsiaj ntawm fauna, thaum raug rau qhov chaw hluav taws xob, kev txhim kho thiab kev loj hlob qeeb, thiab kev ntxhov siab ntau ntxiv. Lawv lub hauv nruab nrab lub cev tiv thaiv kab mob, metabolism yog cuam tshuam, kev ua haujlwm ntawm lub tsev me nyuam muaj peev xwm ua kom tsis muaj zog, mus txog thaum muaj peev xwm ua ntxiv. Kev ua qias tuaj kuj pab txhawb kom muaj kev cuam tshuam ntawm tus naj npawb ntawm cov tsiaj ntawm ntau tus neeg sawv cev hauv tib lub ecosystem.
Kev cai ua raws txoj cai
Txhawm rau txo qib hluav taws xob, hluav taws xob cov kev cai tau siv rau kev ua haujlwm ntawm cov hluav taws xob. Hauv qhov no, nws yog txwv tsis pub siv cov khoom siv nrog cov vuam kab uas muaj siab dua lossis qis dua qhov tau tso cai. Kev siv cov cuab yeej siv hluav taws xob hloov pauv electromagnetic tsis yog saib xyuas los ntawm cov chaw hauv tebchaws thiab thoob ntiaj teb, lub cev tswj hwm thiab Lub Koom Haum Ntiaj Teb Kev Noj Qab Haus Huv.
