what happen if converging rays are made to pass to a convex lens? what happen if divergent rays are made to pass to a concave lens?

According to Faynman Lectures on physics in the chapter of geometrical vol1 ch27, the general rule for the resolution on any optical instrument is this: Two different point sources can be resolved only if one source is focused at such a point that the times for...

Please check The physics book of Marcelo Alonso and Edward J. Finn in the chapter of geometry of waves when talking about telescope

The telescope magnification is given by the measure of the resolution power of the eye divided by the resolution power of the objetive lens. I just want to know why a magnification can be defined as the ratio of these two kinds of resolution, I need a...

Ok, thanks, it also would be interesting to know why the eye only just can accommodate diverging rays.

Why in telescopes and microscopes the ocular distance is such that it creates virtual images instead of real images?

But my optics teacher who is a Ph D in laser physics told me that all of the electromagnetic spectrum is not considered as light, are you sure about that all of the parts of electromagnetic spectrum can be refracted, reflected and travel in straight lines?

I know that light is a form of electromagnetic radiation but I know that all electromagnetic radiation is not light. I know that light has four basic properties: 1) Light travels in straight lines. 2)Light can reflect. 3)Light...

Hey Johng23! is it necessary to know the planes of each structure that generate diffraction to compare with the h^2+k^2+j^2 experimentally pattern obtained by diffraction angules? I Also think is necessary to try different kind of operations with all of the...

In the book of the Dr. Ronald Askeland the problem about x-ray diffraction use the next planes indices to calculate the interplanar distance, but I don't understand why to use such planes indices? Are these planes all of planes in a cubic structure? (111) (200) (211)...
