Refraction and Mirrors, image position

  1. Mar 1, 2009 #1
    1. The problem statement, all variables and given/known data
    A concave mirror (R=54cm) faces a convex mirror of the same radius. The distance between the mirrors is 54cm, and their axes coincide. A candle is held between the mirrors, 10 cm from the convex mirror.
    Consider light rays reflect off the concave mirror and then the convex.
    Where do these rays form an image, in relation to the convex mirror?


    2. Relevant equations
    f= +/- .5R
    1/s + 1/s' = 1/f


    3. The attempt at a solution
    i am not sure where to begin

    Have you drawn the situation yet?

    The principle to keep in mind is that the image of the first mirror becomes the object of the second mirror. Solve the problem as a single concave mirror first, locate the image on your drawing, refigure the object distance to the second mirror, solve again.
