Lub teeb yog dab tsi?

Lub teeb tuaj yeem txhais tau ntau txoj hauv kev.

Ib tug photon, ib tug yoj daim ntawv, ib tug particle, ib tug electromagnetic zaus.Lub teeb coj zoo li ob qho tib si lub cev thiab lub nthwv dej.

Qhov peb xav tias yog lub teeb yog ib feem me me ntawm electromagnetic spectrum hu ua tib neeg pom lub teeb, uas cov hlwb hauv tib neeg lub qhov muag yog qhov nkag siab rau.Feem ntau cov tsiaj ob lub qhov muag yog rhiab rau qhov zoo sib xws.

Kab, noog, thiab txawm tias miv & dev tuaj yeem pom qee yam ntawm UV teeb, thaum qee tus tsiaj tuaj yeem pom infrared;ntses, nab, thiab yoov tshaj cum!

Lub paj hlwb mammalian txhais/decodes lub teeb rau hauv 'xim'.Lub wavelength los yog zaus ntawm lub teeb yog qhov txiav txim siab peb pom xim.Lub wavelength ntev dua zoo li liab thaum lub wavelength luv dua zoo li xiav.

Yog li ntawd, xim tsis yog intrinsic rau lub ntug, tab sis ib tug creation ntawm peb lub siab.Tsuas yog sawv cev ib feem me me ntawm tag nrho cov electromagnetic spectrum.Tsuas yog photon ntawm qee zaus.

Daim ntawv yooj yim ntawm lub teeb yog cov kwj ntawm photons, oscillating ntawm ib lub wavelength tshwj xeeb.
