Hi, I'm preparing for an exam and just came across a problem involving image construction. I know how to construct an image (parallel ray, focal ray, etc.), but I've never seen it done with such a small lens. I can't find anything about it online either. How should I proceed?
Thank you in advance for any help 🙂

Loading...Hi, I recently bought a lamp from the USA on eBay—to be more precise, a lamp stand without a bulb. Could I simply plug the lamp in using an adapter and a German bulb?
Hello everyone, I bought the Lookway "MADA ELITE" dressing table from OTTO a while ago. It has integrated LED lighting with several GTV LED bulbs (model: "GTV LED DC12 1.7W 3000K IP20"). Unfortunately, the main module, or rather the distribution strip that connects the LEDs, is now broken. I've already looked at OTTO, but they…
Radioactive nuclei can release energy and are therefore unstable. This causes them to decay. Mass and nuclear charge play a crucial role in this process. That's basically how far I've got now. However, what I don't understand is why they decay randomly and what happens specifically in the core. Example: We have potassium 42, which…
So if the universe contracts and expands again, and this happens infinitely often, then sooner or later, in one of these countless expansions, it will develop again in the same particle combination that gave rise to us in the current expansion – or will it?
Good evening Today is the first time I've worn soft contact lenses, and when I went to the optician, it took me about 30 minutes to remove one. Now I've been sitting in the bathroom for about three hours and I can't get one out, no matter how I try or how I've been shown…
Can someone please tell me the solution? I don't understand it, and there's a lot of confusing stuff on Google. It's really important. I'm writing an essay about this in two days and I'm running very late. I thank whoever tells me this in advance. Thanks.
Die Ausdehnung der Linse, wie sie in der Skizze eingezeichnet ist, wird hier keine Rolle spielen. Entscheidend ist nur die Ebene, in welcher die Linse liegt.
Es wird vorgegeben, dass man von der Näherung einer dünnen Linse ausgehen darf und (sehr wahrscheinlich auch), dass die Strahlen achsennah verlaufen. Also einfach stur die Bildpunkte konstruieren und nicht von der kleinen Linse irritieren lassen.
Alles klar vielen Dankđź’Ż das macht die Sache einfacher
So ist es. In der Linsengleichung kommt auch nur die Brennweite der Linse vor und nicht der Durchmesser.
