    Types of lens flare - light and optical depth?

    I'm trying to understand what's going on with lens flare in different kinds of lenses. There's a lot of lens flare out there creating weird and wonderful artifacts in people's pictures. Without understanding the kind of lens flare going on in a very flat lens (e.g. smartphone) or a long lens...

    By mixing 3 types of invisible electromagnetic waves, as they pass through a solid ob

    -ject, could the waves raise the electron to a shell level that is the same as glass, so that light cannot be absorbed, to make the object translucent, or transparent. Is it possible for any invisible EM waves, like radio waves, ultraviolet soft, or hard X- Rays, or gamma rays, to be combined...

    Types of motion

    I need exact classification of motion(or hierarchy) so that numerical problem can esily be solved. such as Linear motion. It can further be classified into uniform and non uniform,non uniform can further be classified as motion with constant acceleration or with non uniform acceleration. Or some...
