Rabkin polychromatic itheyibhile umbono test umbala

umbono umbala

Kuba umbono umbala banoxanduva iiseli receptor photosensitive kwiretina - cone. Kukho iindidi ezintathu cone, ezo ngobukhulu uvakalelo ecacicleyo ezifumaneka iinxalenye blue, oluhlaza kunye nobomvu spectrum. Ngenxa iintlobo ezahlukeneyo cone ukuya ezithathu zaseprayimari imibala abantu bakubone amawaka imibala kunye nombala. Ngenxa excitation ngaxeshanye kweentlobo 3 receptors, kukho uza emhlophe.

ukuhlukunyezwa imibala

Kwimeko ukugxojwa okanye buthathaka entsa omnye kwabathathu imibala yokuqala, umntu uyayeka ukuba ukuqonda nawuphi na umbala. Umbono kakuhle ebomvu ekuthiwa Protanopes, eluhlaza - deuteranopia, nemisonto emsi - acyanopsia. Ukutyeshelwa imibala kunokuba iziphene okanye lufundiwe. iimpazamo Rare esizalwa okuqonda indawo eluhlaza umphunga, okanye achromatopsia. Abantu abaninzi abakwazi ukwahlula ebomvu evela oluhlaza, njengoko ukuqonda ezi imibala efana hina. Esi sifo ngokuba imibala umbala umbono. Sisifo yemfuza ixhaphake kakhulu into eyindoda. Kuba lokufunyaniswa ukuphazamiseka usebenzisa polychromatic umbala imvakalelo opticians itafile Rabkin.

Yintoni polychromatic itheyibhile Rabkin

Ezi theyibhile luqulathe amachaphaza ezahlukeneyo umbala amalungiselelo ngendlela ethile ukuba abanye babo ichazwe ngu kucacile amanani okanye amanani zejometri. Kwimeko zokugxojwa imibala isigulane ubona amanani ezifihlakeleyo ayibonakali ngabantu abaqhelekileyo. Ezi theyibhile ukuthatha ingqalelo iintlobo eyamkelekileyo ngokubanzi ukuphazamiseka ngumbono umbala, nto leyo evumela ukuba ukuqinisekisa ngezifo naso okanye lufundiwe. Uphononongo enokwenziwa abadala kunye nabantwana kwiminyaka emi-2 ubudala.

Iindlela zokufunda imibala umbono

• · Isifundo uhleli ukuze umthombo ukukhanya emva komhlana wakho.
• · Tables amalungiselelo nkqo kwinqanaba iliso, kumgama imitha 1 ukusuka sifundo.
• Yohlaziyo etafileni enye nje imizuzwana ngaphezulu kwe-10.
• · Ukuba uvavanyo unxiba iiglasi, ngoko umele kudlule izibuko uvavanyo.
• · Ukuze ubone ukuphazamiseka iziphene uvavanyo ucelwa ukuba uqwalasele itafile ngamehlo ezimbini ngaxeshanye, kunye nokuchonga nokuphazamiseka ezifunyenwe yophononongo olwenziwe iliso khosi ngasekunene nangasekhohlo.
• bayamenywa · Abantwana ukuba wenze isangqa uphawu brush ukuba babone phezu kwetafile.

Ukuhlolwa kweziphumo zokufunda

1. umbono Normal umbala (trihromaziya) - xa kahle amacwecwe 27 thotho engundoqo.
2. umbono umbala engaqhelekanga - ukuba igama ngokungachanekanga 1 - iitafile 12.
3. Ephula umbala umbono ofanayo (dihromaziya) - igama ngokungachanekanga iitafile-12 okanye ngaphezulu.

ukufunda ongakhetha table:

• ilungile
• akunakuqinisekiswa
• engafanele yoqobo
• embi Nedlac
• ukufunda

Kukho iitafile 3 ukuze bakwazi ukufunda abo ngezifo zifumaneka kuphela.
