Photon momentum is delivered by the equation: p=hλ p=h λ.
Koj pom lub zog ntawm photon li cas?
txhawm rau xam lub sijhawm, peb siv qhov sib npaug ntawm Broglie: p=h / lambda. Lub zog ntawm txhua photon yog sib npaug rau Planck qhov tsis tu ncua muab faib los ntawm lub wavelength ntawm lub teeb. Yog li, ntsaws cov lej hauv, uas yog 6.6310^-34 muab faib los ntawm 4.510^-7, uas yog 1.4710^-27 kilogram meters ib ob.
Lub zog ntawm photon ntawm lub zog yog dab tsi?
Photon yog ib hom ntawm cov khoom siv hauv tsev uas muaj qhov xoom so thiab txav nrog lub teeb nrawm hauv lub tshuab nqus tsev. Einstein piav qhia lub zog (p) ntawm photon nrog rau cov qauv muab. Lub zog thiab lub zog ntawm photon muaj feem cuam tshuam los ntawm kev sib npaug. E=pc.
Lub zog lub zog yog dab tsi?
Nyob rau hauv cov cim, linear momentum p txhais tau tias yog p=mv, qhov twg m yog qhov loj ntawm qhov system thiab v yog nws qhov nrawm. SI unit rau lub zog yog kg · m / s. Newton txoj cai thib ob ntawm kev txav mus los ntawm lub zog hais tias lub zog sab nraud sib npaug sib npaug ntawm qhov kev hloov pauv ntawm lub zog faib los ntawm lub sijhawm uas nws hloov pauv.
4-momentum ntawm photon yog dab tsi?
4-momentum txhais tau tias p=mU qhov m yog qhov seem ntawm cov particle thiab U yog 4-ceev.

Txawm li cas los xij, corneal collagen cross-linking - cov txheej txheem qib siab tau pom zoo los ntawm US Food and Drug Administration (FDA) hauv xyoo 2016 - tuaj yeem txhim kho qhov pom kev hauv cov neeg mob txhua hnub nyoog. Corneal collagen cross-linking (CXL) tsis yog kho rau keratoconus, tab sis nws tuaj yeem pab tiv thaiv tus mob kom tsis txhob mob hnyav.
Lub photon twg muaj zog tshaj plaws?
Kev koom tes ntawm Suav thiab Nyij Pooj astrophysicists tau tshaj tawm lub zog siab tshaj plaws photons puas tau pom: gamma rays nrog lub zog txog li 450 trillion electron volts (TeV). Lub photon twg muaj zog tshaj plaws liab lossis xiav?
Puas muaj zog ntawm kev qaug zog ua hauj lwm rau wither?
Ntxoov ntxoo ntawm qhov tsis muaj zog ntawm lub cev pob txha yuav tsum muaj peev xwm qis dualub caij nyoog ntawm nws yuav muab cov nyhuv wither thaum nws tsoo koj; koj tsuas yog yuav tau kev puas tsuaj ntawm ntaj xwb. Pob potions cuam tshuam lub wither?
