  2. Curved mirror - Wikipedia

    en.wikipedia.org/wiki/Curved_mirror

    A convex mirror diagram showing the focus, focal length, centre of curvature, principal axis, etc. A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source. [1] Convex mirrors reflect light outwards, therefore they are not used to focus light.

  3. Launch and commissioning of the James Webb Space Telescope

    en.wikipedia.org/wiki/Launch_and_commissioning...

    The primary mirror segments and secondary mirror were moved away from their protective launch positions. This took about 10 days, because the 132 [57] actuator motors are designed to fine-tune the mirror positions at microscopic accuracy (10 nanometer increments) and must each move over 1.2 million increments (12.5 mm) during initial alignment.

    The largest optical telescope in the world as of 2009 to use a non-segmented single-mirror as its primary mirror is the 8.2 m (27 ft) Subaru telescope of the National Astronomical Observatory of Japan, located in Mauna Kea Observatory on Hawaii since 1997; [3] [better source needed] however, this is not the largest diameter single mirror in a telescope, the U.S./German/Italian Large Binocular ...

  5. Parabolic reflector - Wikipedia

    en.wikipedia.org/wiki/Parabolic_reflector

    A parabolic (or paraboloid or paraboloidal) reflector (or dish or mirror) is a reflective surface used to collect or project energy such as light, sound, or radio waves. Its shape is part of a circular paraboloid , that is, the surface generated by a parabola revolving around its axis.

  6. Mirror - Wikipedia

    en.wikipedia.org/wiki/Mirror

    A mirror reflecting the image of a vase A first-surface mirror coated with aluminium and enhanced with dielectric coatings. The angle of the incident light (represented by both the light in the mirror and the shadow behind it) exactly matches the angle of reflection (the reflected light shining on the table). 4.5-metre (15 ft)-tall acoustic mirror near Kilnsea Grange, East Yorkshire, UK, from ...

  7. Infinity mirror - Wikipedia

    en.wikipedia.org/wiki/Infinity_mirror

    A self-contained infinity mirror used as a wall decoration. In a classic self-contained infinity mirror, a set of light bulbs, LEDs, or other point-source lights are placed around the periphery of a fully reflective mirror, and a second, partially reflective "one-way mirror" is placed a short distance in front of it, in a parallel alignment.
