dzontra.volta Posted April 27, 2007 Report Share Posted April 27, 2007 Relativistcka masa: Svima nam je poznata formula: -sto znaci da masa cestice na brzinama pribliznim svetlosti tezi beskonacnosti -fotoni se krecu brzinom svetlosti da li to znaci da je njihova masa beskonacno mala ili da ovde nesto nestima? neka logika sa grafika (koji bi opet svi trebalo da znaju ) je da je masa beskonacna => fotoni bi trebalo da imaju neizmernu masu...

Dule_smor Posted April 27, 2007 Report Share Posted April 27, 2007 koliko ja znam fotoni su cestice bez mase, tj njihova masa mirovanja je 0...tako da ta formula ne vazi u ovom slucaju...ali ne drzite me za rec, ta kvantna fizika je veoma varljiva nauka:)...ako bas hocete mogu da pitam tomketa:) Link to comment Share on other sites More sharing options...
dzontra.volta Posted April 27, 2007 Author Report Share Posted April 27, 2007 pitaj :)) cestica bez mase zvuci nemoguce osim da je masa beskonacno mala zbog formule gore... hmmmz Link to comment Share on other sites More sharing options...

bolkonski Posted April 27, 2007 Report Share Posted April 27, 2007 Naravno da fotoni nemaju masu i dualne su prirode, sto ce reci da su u isto vreme i cestice i talasi. ----------------- nema vise zezanja A.B. Link to comment Share on other sites More sharing options...
f4ts0 Posted April 27, 2007 Report Share Posted April 27, 2007 Nisu fotoni dualne prirode vec svetlost. Fotoni su nosioci mase mada mozda sam i prolupao davno bese.

dvnityCker Posted April 28, 2007 Report Share Posted April 28, 2007 siriuslu nau, nepostojanje vece brzine od brzine svetlosti je logicki apsurd nastao ogranicenoscu ljudskog mozga i nedovoljnim stepenom poznavanja svemira, dimenzija, vremena i ostalih stvari za koje smo vezani. (ne kazem da je einstein strogo ogranicen, vec generalno ljudi kao bica) The people can always be brought to the bidding of the leaders. That is easy.

De1Rekt0n Posted April 28, 2007 Report Share Posted April 28, 2007 Svetlost je dualne prirode kao sto ste vec rekli i to je otkrio Thomas Young, po meni najveci covek koji je ikada ziveo, bitna stvar je da su photoni invarijantne prirode sto znaci da putuju uvek konstantom c, anyway neko je rekao vec fotonima je masa 0 i to je tacno, cela teorija je veoma komplikovana i treba puno vremena da se shvati. u pravu si dule, nauku ne poznajem dobro mogao bi da isfilozofiram kretanje i brzinu no necu da vam gusim topik, tako da se povlacim na stranu Einstein nije rekao da je nemoguce da nesto moze putovati vecom brzinom od C vec je rekao da nista sto ima masu ne moze putovati vecom brzinom od C, sto je svakako istina.

f4ts0 Posted April 28, 2007 Report Share Posted April 28, 2007 (edited) Fotonima nije masa 0 vec beskonacno mala To jest nema masu, ali ima moment, a neka trtljanja koja sam bio primoran da slusam su objasnjavala kako ne moze biti momenta sa masom BAS 0 vec beskonacno malom Mada opet mozda gresim, ne zelim da se podsecam, fizika mi nije donela nista dobro u zivotu :) Cak ni 20 fizika koje sam morao da polozim :) Edited April 28, 2007 by f4ts0 You may have gone to Cambridge, but I'm an honorary graduate of Starfleet Academy Link to comment Share on other sites More sharing options...

Da naravno kad se teoretise onda nije 0 vec je beskonacno mala, i kod hemije mi smo ucili one orbitale a na kraju to nema veze smozgom nego imas verovatnocu da se nesto zadesi na nekom mestu.

f4ts0 Posted April 28, 2007 Report Share Posted April 28, 2007 Hah dali si ti svestan kolko je velika razlika izmedju 0 i beskonacno mala. Prakticno razlika je tolka da nikad ne polozis matemetiku i razne fizike ako izjednacis 0 i beskonacno mala.

Pazi rekao sam 0 jer ne postoji masa kod fotona a to sto si rekao da je beskonacno mala opet ne stoji jer foton nema masu nego ima samo momenat, jednostavno kod fotona ne postoji masa i tacka! :D Link to comment Share on other sites More sharing options...

~JungleBoY~ Posted April 29, 2007 Report Share Posted April 29, 2007 (edited) Niko nije ni rek'o da jesu. Kol'ko sam ja upoznat,masa mirovanja fotona je nula. A moment im se beše računa preko plankove konstante, redukovane valjda, a masa ne sudeluje nigde, pa ne vidim zašto bi bi morali da apstraktujemo da je beskonačno mala. Al' ponovo, daleko sam ja od kraja faksa, pa ne bi' da protivurečim pertuu diplomcu, sva je prilika da zna nešto više, al' neće kaže, govedo Edited April 29, 2007 by ~JungleBoY~ :-) Link to comment Share on other sites More sharing options...
