Lom Svetla a Optické Šošovky
1 / 9
Úvod do lomu svetla a šošoviek
Lom svetla je úplne všade okolo nás a bez neho by sme ani nevedeli vidieť! Je to jav, keď sa svetlo ohne alebo zmení smer pri prechode z jedného materiálu do druhého.
Predstav si to ako prechádzanie z chodníka do blata - spomalíš a možno sa aj trochu zmení tvoj smer. Svetlo sa správa podobne - keď prejde napríklad zo vzduchu do vody, zmení rýchlosť a ohne sa.
Vďaka tomu rozumieme, prečo veci vyzerajú inak pod vodou, ako fungujú mikroskopy alebo prečo vidíme dúhu. Optika je všade - v našich očiach, fotoaparátoch aj okuliariach!
Tip: Skús si doma dať ceruzku do pohára s vodou a pozri, ako sa "zlomí" kvôli lomu svetla!
Kľúčové pojmy a definície
Lom svetla vzniká, keď svetlo prechádza z jedného priehľadného materiálu do druhého a zmení svoju rýchlosť. To spôsobí, že sa svetelný lúč ohne.
Index lomu je číslo, ktoré hovorí, ako veľmi sa svetlo spomalí a ohne v konkrétnom materiáli. Vzduch má index skoro 1, voda asi 1,33 a sklo okolo 1,5.
Šošovka je priehľadné teliesko so zakrivením, ktoré dokáže zbiehať alebo rozbiehať svetelné lúče. Optická os je priamka prechádzajúca stredom šošovky, optický stred je bod, cez ktorý lúče prechádzajú bez ohnutia.
Ohnisko je špeciálny bod, kde sa stretávajú alebo odkiaľ sa zdajú vychádzať svetelné lúče. Ohnisková vzdialenosť je vzdialenosť od stredu šošovky k ohnisku.
Zapamätaj si: Čím väčší index lomu, tým viac sa svetlo ohne!
Typy šošoviek - Spojka
Spojka (konvexná šošovka) je hrubšia v strede a tenšia na okrajoch - vyzerá ako "buclatá". Zbiera rovnobežné svetelné lúče a ohýba ich tak, aby sa stretli v jednom bode za šošovkou.
Spojka môže vytvárať dva typy obrazov. Skutočný obraz sa dá zachytiť na tienidle (ako vo fotoaparáte), zdanlivý obraz vidíme len okom (ako pri lupe).
Používa sa všade okolo nás - v lupách, okuliariach pre ďalekozrakých ľudí, objektívoch fotoaparátov, mikroskopoch aj ďalekohľadoch.
Keď si blízko k predmetu, spojka ho zväčší. Keď si ďalej, vytvorí menší, ale skutočný obraz na druhej strane.
Fakt: Tvoje oko funguje presne ako spojka - zaostruje svetlo na sietnicu!
Typy šošoviek - Rozptylka
Rozptylka (konkávna šošovka) je tenšia v strede a hrubšia na okrajoch - vyzerá "štíhlo". Na rozdiel od spojky svetelné lúče nezbiera, ale rozptyľuje ich.
Rozbiehajúce sa lúče sa zdajú vychádzať z jedného bodu pred šošovkou - to je jej ohnisko. Rozptylka vždy vytvára len zdanlivý obraz, ktorý je menší a vzpriamený.
Hlavne ju používajú ľudia s krátkozrakosťou - tí, čo zle vidia do diaľky. Rozptylka rozptýli svetelné lúče predtým, ako vstúpia do oka, takže oko ich potom dokáže správne zaostriť.
Nájdeš ju aj v hľadáčikoch fotoaparátov alebo niektorých typoch ďalekohľadov.
Tip na zapamätanie: Spojka zbiera, rozptylka rozptyľuje - jednoduché!
Zobrazovanie šošovkami
Na kreslenie obrazov používame konštrukčne lúče - špeciálne lúče, ktorých dráhu vieme ľahko nakresliť. Pre spojku sú tri základné pravidlá.
Lúč rovnobežný s osou sa po prechode šošovkou láme a ide cez ohnisko. Lúč cez optický stred pokračuje rovno. Lúč cez ohnisko pred šošovkou sa po prechode láme a ide rovnobežne s osou.
Pri rozptylke funguje to podobne, ale opačne. Rovnobežný lúč sa láme tak, akoby vychádzal z ohniska na tej istej strane. Lúč cez stred ide stále rovno.
Pomocou týchto pravidiel dokážeš nakresliť, ako bude vyzerať obraz akéhokoľvek predmetu.
Skús si to: Nakreslite si šošovku a skúste použiť tieto pravidlá na papieri!
Riešené príklady z bežného života
Zlomená ceruzka vo vode je klasický príklad lomu svetla. Svetlo z časti ceruzky pod vodou sa láme inak ako zo vzduchu, takže náš mozog vníma ceruzku ako "zlomenú".
Lupa funguje ako spojka s krátkou ohniskovou vzdialenosťou. Keď ju držíš blízko predmetu, vytvorí zväčšený zdanlivý obraz, preto vidíš malé písmenká väčšie.
Okuliare na korekciu zraku sú geniálne jednoduché. Krátkozrakí ľudia používajú rozptylky, ktoré rozptýlia svetlo pred vstupom do oka. Ďalekozrakí používajú spojky, ktoré svetlo zbíhajú.
Všetko je to o tom, aby sa svetlo zaostrilo presne na sietnicu v tvojom oku!
Zaujímavosť: Ryby vo vode sa zdajú bližšie k povrchu, než skutočne sú - opäť kvôli lomu svetla!
Rýchly súhrn na test
Lom svetla vzniká pri prechode svetla medzi rôznymi materiálmi kvôli zmene rýchlosti. Index lomu hovorí, ako veľmi sa svetlo ohne.
Spojka (hrubšia v strede) zbiera lúče, vytvára skutočné aj zdanlivé obrazy, používa sa v lupách a okuliariach pre ďalekozrakých. Rozptylka (tenšia v strede) rozptyľuje lúče, vždy vytvára zdanlivý obraz.
Ohnisko a ohnisková vzdialenosť sú kľúčové vlastnosti každej šošovky. Konštrukčné lúče ti pomôžu nakresliť, ako šošovka vytvorí obraz.
Zapamätaj si: spojka zbiera, rozptylka rozptyľuje svetlo!
Na záver: Optika je všade okolo nás a pochopenie týchto základov ti pomôže rozumieť, ako funguje svet!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.
Samantha Klich

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend
