  2. Vulva - Wikipedia

    en.wikipedia.org/wiki/Vulva

    Vulva. In mammals, the vulva ( pl.: vulvas or vulvae) consists of the external female genitalia. The human vulva includes the mons pubis, labia majora, labia minora, clitoris, vulval vestibule, urinary meatus, vaginal opening, hymen, and Bartholin's and Skene's vestibular glands. The vulva includes the entrance to the vagina, which leads to the ...

    en.wikipedia.org/wiki/Prism_(Japanese_band)

    Prism was formed in 1975 by Akira Wada and Ken Watanabe. In 1976, the group were signed to Polydor Records and toured nationwide. Prism released their debut album in 1977, Prism, which ran out of stock after its release. [1] Shortly after, the band went on to support Eric Clapton at the Budokan. Their 1986 song 'Take Off' was featured in a Mild ...

  4. Dye laser - Wikipedia

    en.wikipedia.org/wiki/Dye_laser

    A diffraction grating is used as the high-reflector (upper yellow beam, left side). The two meter beam is redirected several times by mirrors and prisms, which reduce the overall length, expand or focus the beam for various parts of the cavity, and eliminate one of two counter-propagating waves produced by the dye cell.

  5. Prism (geometry) - Wikipedia

    en.wikipedia.org/wiki/Prism_(geometry)

    An oblique prism is a prism in which the joining edges and faces are not perpendicular to the base faces. Example: a parallelepiped is an oblique prism whose base is a parallelogram, or equivalently a polyhedron with six parallelogram faces. Right Prism. A right prism is a prism in which the joining edges and faces are perpendicular to the base ...

  6. Laser pointer - Wikipedia

    en.wikipedia.org/wiki/Laser_pointer

    A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot. The small width of the beam and the low power of typical laser pointers make the beam itself invisible in a ...

  7. Ring laser gyroscope - Wikipedia

    en.wikipedia.org/wiki/Ring_laser_gyroscope

    Ring laser gyroscope. A ring laser gyroscope ( RLG) consists of a ring laser having two independent counter-propagating resonant modes over the same path; the difference in phase is used to detect rotation. It operates on the principle of the Sagnac effect which shifts the nulls of the internal standing wave pattern in response to angular rotation.

  8. Prism spectrometer - Wikipedia

    en.wikipedia.org/wiki/Prism_spectrometer

    Prism spectrometer. A prism spectrometer is an optical spectrometer which uses a dispersive prism as its dispersive element. The prism refracts light into its different colors ( wavelengths ). The dispersion occurs because the angle of refraction is dependent on the refractive index of the prism's material, which in turn is slightly dependent ...

    en.wikipedia.org/wiki/Machine_element

    Machine element or hardware refers to an elementary component of a machine. These elements consist of three basic types: structural components such as frame members, bearings, axles, splines, fasteners, seals, and lubricants, mechanisms that control movement in various ways such as gear trains, belt or chain drives, linkages, cam and follower ...
