Homework Help: Simple Optics Question

  1. Jan 28, 2010 #1
    1. The problem statement, all variables and given/known data
    I am given a question with the focal length stated in optical power
    i.e 6.7m-1

    what is optical power it is stated that it is = to 1/f

    so in the equation 1/p + 1/q = 1/f
    is it right to assume that 1/p + 1/q = 6.7
    or is it 1/6.7

    2. Relevant equations

    3. The attempt at a solution

    Yes, optical power is defined as 1/f for the lens.
    Your first assumption is correct.
    1/p + 1/q = power of lens
