Largest reflection angle

  1. Dec 8, 2013 #1

    I'm having a problem with one assignment and I would really need som help. The question is:

    The Chandra X-ray telescope is used for observations in the 0.1-10 keV range. Focal
    length is 10 m, max mirror radius is 0.6 m. What is the largest reflection angle in the optics
    (assuming that both reflections are of the same size)?

    I started first to find the wavelength by using the E=hc/λ formula. I got 12,4082 nm. After that, I'm stuck...Glad if anyone could help :)
