While both convex and concave relate to some type of curve, they are never used to refer to the same type of curve. However, it is usually possible to classify just about any incidence of curve as either convex or concave. In order to understand the difference between convex and concave ...
Lens is a transmissive optical device that is used to focus or disperse light beams by the phenomenon called refraction. A lens could either be concave or convex and an example of application of lens is its used it camera. Key Ideas:The earliest forms of lenses were developed in Egypt and...
Concavelenses—those that are thicker around the edges than they are in the center—disperselight rays, which can have the effect of making things look smaller or farther away.Convexlenses—those that dome outward and are thicker in the center than they are around the edges—make light rayscon...
Just like concave, convex can be used as a noun for a surface or line that curves outward, and it also has a use in geometry, where it describes a polygon with interior angles less than or equal to 180°. Finding a mnemonic device for to remember the difference is easy enough. There...
When the rays are produced backwards in a virtual way, they meet at a point. This is the prime difference between concave and convex lens. If you follow the equation of the focal length and object distance, you will find that the image distance always comes negative. It means that the ...
