Yog tias khoom yog tsiv rau koj , thewaves yog compressed, yog li lawv wavelength luv dua. Yog tias khoom yog txav deb ntawm koj , cov nthwv dej yog stretched tawm, yog li lawv wavelength yog ntev dua. Cov kab yog hloov mus ntev (redder) wavelengths --- qhov no hu ua aredshift.

Ib yam li ntawd, tib neeg nug, dab tsi yog hais txog kev hloov pauv ntawm lub wavelength uas tshwm sim thaum ib qho khoom txav mus rau lossis tawm ntawm qhov chaw?

Cov lus teb yog doppler nyhuv. nws qhov nce lossis txo qhov zaus ntawm lub suab, lub teeb, lossis lwm yam nthwv dej raws li qhov qhov chaw thiab soj ntsuam txav mus los yog deb los ntawm ib leeg. Piv txwv yog thaum tam sim ntawd hloov nyob rau hauv lub suab yog pom nyob rau hauv ib tug passingsiren.

Tsis tas li ntawd, tus kws tshawb fawb nto moo twg thawj zaug siv lub tsom iav raj rau kev soj ntsuam astronomical? Galileo Galilei

Raws li, yam xim twg muaj zog tshaj photons?

Liab los yog violet yog lub xim nrog rau feem ntau muaj zog photons !!

Qhov twg ntawm lub hnub nyob ncaj qha saum qhov chaw pom?

Photosphere yog pom saum npoo ntawm Hnub . Thesolar cua muaj xws li chromosphere thiab corona.
