A concave or diverging lens spreads out the parallel light rays passing through it. A concave lens and its corresponding ray diagram include the focal point, focal length, and principals axis. The focal point, F, of a concave lens is the point where all refracted light rays seem to emerge...
In ray diagrams, it is automatically assumed that thin lenses are used. A thin lens is characterized by a very small diameter compared to the radii of the two surfaces. It allows the light to refract once but does not include any aberration or dispersion of light. In addition, all light ...

Homework Statement An object is in the focal length of a convex lens. As the object is moved from the focus towards the lens, what happens to the object? Homework Equations 1/f=1/d0+1/di The Attempt at a Solution I know how to solve this problem using ray diagrams, and the solution...
The X-ray Diffraction pattern shown in Figure S2 illustrated that the as-obtained bimetallic Pt/Cu concave nanocrystals were indexed to Pt/Cu alloy whose peaks were near by the peaks of CuPt alloy compound. To further confirm the structure of the Pt/Cu hexapod concave nanocrystals, the high-...
