At the bottom of the periscope, the light strikes another mirror and is then reflected into the viewer's eye. This simple periscope uses only flat mirrors as compared to the periscopes used on submarines, which are usually a complex optical system using both lenses and mirrors.
Concave mirror is used in flood light.
So usually when you shave, you hold the mirror up close right.
Shaving Mirror:Concave mirrors are converging mirrors. you'll be holding it between its focal length and the mirror so the image would be upright and magnified.
A kaleidoscope is an optical instrument with two or more reflecting surfaces tilted to each other in an angle, so that one or more (parts of) objects on one end of the mirrors are seen as a regular symmetrical pattern when viewed from the other end, due to repeated reflection. The reflectors (or mirrors) are usually enclosed in a tube, often containing on one end a cell with loose, colored pieces of glass or other transparent (and/or opaque) materials to be reflected into the viewed pattern. Rotation of the cell causes motion of the materials, resulting in an ever-changing viewed pattern.
A convex mirror is used as a reflector in a street light because it diverges rays oflight over large area.
The headlamp's concave mirror is open on one end, and the light bulb's filament is placed at or near the focus. Parallel ight rays, if they were coming into theheadlamp from outside (say, the driver is driving his car in the direction of the setting sun), would converge near the filament of the light bulb.
