Refraction yog qhov hloov pauv ntawm cov nthwv dej uas tshwm sim thaum nthwv dej taug kev ntawm ib qho nruab nrab mus rau lwm qhov. Refraction yog ib txwm nrog lub wavelength thiab ceev hloov. Diffraction yog qhov khoov ntawm nthwv dej ncig obstacles thiab qhib. Tus nqi ntawm kev txawv txav nce nrog nce wavelength.

Ntxiv mus, qhov sib txawv ntawm refraction yog dab tsi?

Qhov yooj yim qhov sib txawv ntawm kev xav thiab refraction yog qhov Reflection ntawm lub teeb yog cov txheej txheem uas lub teeb bounces rov qab rau ntawm qhov chaw, thaum refraction ntawm lub teeb yog txheej txheem uas lub teeb hloov nws cov kev taw qhia thaum nws dhau los ntawm ib qho nruab nrab mus rau lwm qhov nruab nrab.

Dab tsi yog qhov txawv ntawm refraction thiab dispersion? Refraction hais txog ib qho kev khoov ntawm nthwv dej vim muaj kev hloov ceev. Thaum cov dej ntws tawm mus txawv qhov tob, nthwv dej tau hais tias yog refracted . Dispersion hais txog qhov zaus dependence ntawm refraction . Hauv cas lub teeb refracted los ntawm prism, kev tawg txhais tau hais tias lub teeb ntau zaus khoov ntau dua.

Kuj Paub, qhov txawv ntawm qhov sib txawv thiab cuam tshuam yog dab tsi?

Diffraction tshwm sim thaum nthwv dej ntsib ib qho teeb meem los yog ib qho kev txiav cov cwj pwm no tau nthuav tawm thaum nthwv dej ntsib ib qho teeb meem los yog ib qho slit uas piv rau qhov loj me rau nws lub wavelength, whereas Kev cuam tshuam yog qhov tshwm sim qhov twg nthwv dej sib ntsib thiab sib xyaw ua ke los yog substractively rau daim ntawv

Dab tsi ua rau refraction?

Lub teeb refracs thaum twg nws mus ntawm lub kaum sab xis mus rau hauv ib yam khoom nrog ib qho txawv refractive index (optical ntom). Qhov kev hloov pauv no yog ua rau los ntawm kev hloov ceev. Piv txwv li, thaum lub teeb tawm ntawm huab cua mus rau hauv dej, nws qeeb qeeb, ua rau nws mus txuas ntxiv mus ntawm lwm lub kaum sab xis lossis kev taw qhia.
