Electromagnetic hluav taws xob yog ib hom zog uas feem ntau hu ua lub teeb. Feem ntau hais lus, peb hais tias lub teeb nkag mus rau hauv nthwv dej , thiab tag nrho cov hluav taws xob electromagnetic taug kev ntawm tib ceev uas yog hais txog 3.0 * 108 meters ib thib ob los ntawm a lub tshuab nqus tsev.
Hauv kev hwm rau qhov no, cov yam ntxwv twg zoo ib yam rau txhua qhov hluav taws xob hauv lub tshuab nqus tsev?
Thaum taug kev hauv lub tshuab nqus tsev, cov hluav taws xob nthwv dej los ntawm electromagnetic spectrum tag nrho taug kev tib yam ceev . Kev nrawm yog ceev nrog kev taw qhia, yog li lawv txhua tus yuav taug kev ntawm tib lub nrawm, hais lus tiag tiag. Tab sis zaus thiab wavelength txawv heev.
Vim li cas txhua qhov hluav taws xob hluav taws xob muaj qhov ceev tib yam? Ceev , Wavelength, thiab Zaus The ceev ntawm a yoj yog ib yam khoom ntawm nws lub wavelength thiab zaus. Vim tag nrho cov electromagnetic tsis taug kev ntawm tib ceev dhau qhov chaw, a vuag nrog luv wavelength yuav tsum muaj ntau zaus, thiab vice versa.
Ib sab saum toj no, hom dab tsi ntawm electromagnetic yoj taug kev nrawm tshaj plaws hauv lub tshuab nqus tsev?
xov tooj cua
Dab tsi yog qhov ceev ntawm electromagnetic nthwv dej hauv lub tshuab nqus tsev?
Electromagnetic tsis yog tsim los ntawm kev vibration ntawm tus nqi hluav taws xob. Qhov kev vibration no tsim ib yoj uas muaj ob qho tib si hluav taws xob thiab cov khoom sib nqus. Ib electromagnetic yoj thauj nws lub zog los ntawm a lub tshuab nqus tsev ntawm a ceev 3.00 x 108 m/s (ib ceev tus nqi feem ntau sawv cev los ntawm lub cim c).

Vim li cas qhov ceev ntawm lub teeb tsis tas li nyob rau hauv tag nrho cov ntaub ntawv siv?
Puas yog vim li cas qhov ceev ntawm lub teeb yog qhov tsis tu ncua nyob rau hauv tag nrho cov ntaub ntawv siv? Qhov tsuas yog qhov uas cuam tshuam qhov ceev ntawm lub teeb yog qhov ntsuas qhov nruab nrab ntawm qhov nruab nrab uas nws txav mus, thiab rau qhov chaw khoob, tus lej no yog 1.000000 thiab muab qhov siab tshaj plaws ntawm lub teeb rau koj
Muaj pes tsawg guanine bases puas yog 50 lub hauv paus khub ob txoj hlua DNA 100 bases tag nrho muaj yog tias nws muaj 25 adenine bases?
Yog li, muaj tag nrho ntawm 25 + 25 = 50 adenine thiab thymine hauv tag nrho. Qhov ntawd tawm 100− 50 = 50 seem hauv paus. Nco ntsoov tias cytosine thiab guanine daim ntawv cog lus nrog ib leeg, thiab yog li lawv sib npaug ntawm cov nyiaj. Tam sim no peb tuaj yeem faib los ntawm 2 kom tau txais tus lej ntawm guanine lossis cytosine hauv paus
Puas yog tag nrho cov electromagnetic tsis muaj tib lub amplitude?
Cov lus teb tsis yog qhov amplitude vim qhov amplitude muaj feem xyuam rau qhov siv ntawm electromagnetic teb, uas yog lub square ntawm lub amplitude. Yog li ntawd, ntau qhov chaw ntawm lub teeb muaj ntau dua amplitudes. Tag nrho cov electromagnetic tsis muaj qhov ceev tib yam, c, uas yog qhov ceev ntawm lub teeb
Lub ntiaj teb yuav hloov li cas yog tias cov nyhuv tsev cog khoom tsis muaj nyob rau hauv tag nrho cov lus nug?
A) Yog tsis muaj cov nyhuv tsev cog khoom, lub ntiaj teb yuav tawg tag nrho nws cov cua sov rau hauv qhov chaw. b) Txhua lub hnub ci hluav taws xob tuaj yeem nqus tau yam tsis muaj lub tsev cog khoom. C) Qhov tshwm sim ntawm tsis muaj cov nyhuv tsev cog khoom yuav yog lub ntiaj teb kub heev uas yeej tsis txias
Puas yog qhov ceev yog ib txoj kev txhim khu kev qha ntawm kev txheeb xyuas tag nrho cov khoom tsis paub?
Koj tuaj yeem txheeb xyuas cov khoom tsis paub los ntawm kev ntsuas nws qhov ntom thiab sib piv koj cov txiaj ntsig rau cov npe paub qhov ntom ntom. Qhov ntom = loj / ntim. Xav tias koj yuav tsum txheeb xyuas cov hlau tsis paub. Koj tuaj yeem txiav txim siab qhov loj ntawm cov hlau ntawm qhov ntsuas
