    A pentaprism is a five-sided reflecting prism used to deviate a beam of light by 90°.

    @Mods, I think my score, until now, shud be around 19 or 20, counting the live quiz(not sure exactly how much) with 3 wrong. Its fine the way it is, if its too much of a pain to verify.

    A pentaprism is a five-sided reflecting prism used to deviate a beam of light by 90°.A variant of this prism is the roof pentaprism which is commonly used in the viewfinder of single-lens reflex cameras. In this case, the image needs to be reflected left-to-right, as the prism transmits the image formed on the camera’s focusing screen, which is itself reflected by the reflex mirror in the camera body.

    A pentaprism is used in cameras, as part of the viewfinder mechanism.

    Prism. First image shows major internal reflection. Must be the kind they put in optical mice.

    PentaPrism, used in photography to deviate light by 90 degrees.

    More from wikipedia
    A pentaprism is a five-sided reflecting prism used to deviate a beam of light by 90°. The beam reflects inside the prism twice,[1] allowing the transmission of an image through a right angle without inverting it (that is, without changing the image’s handedness) as an ordinary right-angle prism or mirror would.
