I'll try Goldstein then

Hello, I'm a second year physics student. We are going to use "hand and finch analytical mechanics", however the reviews I saw about this book are bad. I've already taken calculus for mathematicians, linear algebra, classical mechanics, special relativity, and electromagnetism. The topics it...

I'm sure you can do it, mspaint for the win! This is maybe the only way I can get what you are saying. And I'm sure you are pretty.

Can you maybe draw a ray diagram for better understanding of this?

Thanks! In the first link you sent me there they have the eyepiece reverted unlike in my image. Does it matter? I think the refraction should be the same. I'll definitely check that last web out, although it may take some time.

I'm confused about the theory of the telescope I am making. My questions are: 1. Magnification - according to my image we should see magnification because the image we see is the image formed by the continuation of the dotted lines. Is that true? 2. Why do we need lenses with different size? If...

Let's stay outside the experiment and just try to get the right ray diagram. I think they have a mistake in the concave lens. If you can get a correct ray diagram or correct theirs, and explain me why they think the object on the screen is real and the one that we don't see is the virtual one, I...

I'm sorry, I tried drawing it multiple times, with no success. Acctually I'm sure the 2 top lines are not according your convention, but they are good. Third one is a mistake. I found one diagram according to your conventions, but it looks really not accurate...

"Only if separate points of the object end up on separate points of the image (and nowhere else) can you have a sharp picture." That is exactly what I was looking for! Thank you!

Firstly, thank you for the answers. I understand this part. Maybe I better ask: What does really make me think it is blurry? You say that the more lines meet the more focus achieved. If less lines are meeting then it is blurry, and some are of the object is spread around the screen (for example...

Yes, but the image created is created at the screen, where the rays meet, not where the dashed lines meet. The dashed line meeting is where image would have been if no concave lens.

Can you give me more info about "underexposed area"? if we have the top object spread upon an area, I still don't get why it is blurry.

Is this correct? The object on the screen is real object for the concave lense and the object before the screen is virtual object for the concave lens.

Is this correct? The object on the screen is real object for the concave lense and the object before the screen is virtual object for the concave lens.

Homework Statement I have a few fundamental questions in optics about the focus and blurry images. Each textbook says that according to this picture the object image is the same. 1) If we move the screen to point further then the image will be blurry. What causes it to be blurry? 2) Why do...
