Angular resolution of microscope

  1. Apr 18, 2016 #1
    1. The problem statement, all variables and given/known data
    擷取1.PNG

    2. Relevant equations
    θ =1.22λ/d

    3. The attempt at a solution
    for (a) θ =1.22λ/d
    θ =1.22(579nm)/(1.2cm)

    θ =5.8865x10^-5 degree= 1.027x10^-6 rad but the answer =2x10^-3rad ,
    for the micorscope, the formula of angular resolution is different?
    i find that NA=nsina (but how can i link with λ and d?)

    your formula for theta seems to be correct -check the results once again.

    YES, it is right, the answer is 5.8865x10^-5 rad
