Homework Equations

θ =1.22λ/d

The Attempt at a Solution

for (a) θ =1.22λ/d
θ =1.22(579nm)/(1.2cm)[/B]
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.
