### device | reflector:

Mirror
* All mirrors are magic mirrors.
* Most mirrors are made of glass
  - bend light
  - capture light
  - create images
  - have symmetry
* Some mirrors create beams
  - laser beams
* Some mirrors create red beams
  - have holders
* add magic to a room.
* adjust for persons of any height.
* also help by reflecting light and limiting the appearance of shadows
  - serve to 'rob the soul' according to old tradition
* always reflect laser beams at right angles.
* are also effective stimulants because they give a baby an ever-changing view of the world
  - an easy and beautiful way to add light and space to a room
  - cheaper than photo cells
  - essential for safe travel on public roads
  - everywhere
  - high-relfection dielectric type and usually transparent to visible light
  - just one of the many types of appliques used to decorate garments and accessories
* are located in bedrooms
  - cars
  - closets
  - gyms
  - houses
  - purses
  - walls
  - plate glass
  - specular devices that can change the direction a light beam
  - surfaces
* are the doors by which Death comes and goes
  - instruments of vanity
  - way into other worlds
* are used for light reflection
  - spectators
  - usually heavier than pictures or paintings of equal size
  - very smooth and shiny
* avoid the problem of chromatic aberration.
* can also magnify objects
  - be great fun for pets, who often think their reflections are other animals
  - break, or they can deteriorate over time
  - enable a bus driver to observe vulnerable areas of the vehicle
  - play a vital part in creating the impression of extra space
  - replace artwork on walls to make small spaces look bigger
  - trigger delusional behavior in some
* collect light better than lenses.
* come in several different varieties.
* concentrate the light into a laser beam.
  - the illusion of space
* focus sunlight on a boiler, which generates steam and then electricity.
* have no time to waste on reflection
  - some de-silvering on the outer edges due to salt water intrusion
* helps baby practice expressions and discover sense of self.
* increase the sense of spatial illusion.
* occur in fish scales, butterfly wings, and in eye designs in various forms of life.
* often are difficult to get close to, especially for people who use a wheelchair.
* preserve the phase of reflected light.
* reflect light.
* reverse one dimension at a time.
* rotate to create multiple beams that scan across the floor.
* seem to have been common items of commerce during the Middle Ages.
* vary slightly in design.
* work by reflecting light.

### device | reflector | mirror:

Convex mirror
* form only virtual images that are diminished in size.
* reflect images that are smaller than life-sized.
* show a wider area than flat mirrors.

Curved mirror
* produce different images
  - the effect of enlarging or reducing
* track the sun and focus the rays to heat oil in pipes.

Dichroic mirror
* act as filters by transmitting or reflecting unwanted light away.
* separates excitation and emission light paths.

Large mirror
* help reduce blind spots.
* make rooms appear larger and reflect good chi if placed correctly.

Liquid mirror
* are interesting in other areas of science besides astronomy.
* can be a low cost alternative to conventional large telescopes.

Plane mirror
* Most plane mirrors have symmetry.
* can only have virtual images, to get a real image one needs curved mirrors.

Speculum
* are medical devices
* come in different diameters
  - many sizes and can be used for any woman, whether a virgin or sexually active

Spherical mirror
* experience spherical aberration.
* have an aberration.
